Hitachi to Release H8S/2633F and Two Other 16-bit Single-Chip Microcomputer Models with 256-kbyte On-Chip Flash Memory

- Large 256-kbyte flash memory and comprehensive peripheral I/O functions -

Hitachi, Ltd.(NYSE:HIT) today announced the release of the H8S/2633F general-purpose, high-performance microcomputer for storage devices such as CD-R and DVD-RAM and mobile devices such as cellular phones, as the top-end model in the H8S series of 16-bit microcomputers. The H8S/2633F is a 120-pin F-ZTAT^TM*1microcomputer with large 256-kbyte on-chip flash memory, employing a 0.35 micrometers process for the first time in the H8S series. Sample shipments will begin in December 1998. In addition, sample shipments of the 144-pin H8S/2338F will also begin in December 1998, and sample shipments of the 100-pin H8S/2238F will begin in March 1999 in Japan.
In the field of electronic products with embedded microcomputers, there is a demand for field-programmability that enables easy reprogramming or adjustment of microcomputer programs in all stages from development through trial production, production startup, and mass production, in order to provide for increased program size, shorter product development time, improvements in product specifications, and adjustment of control data. Product portability has also brought a demand for microcomputers supporting a variety of power-down modes.

Having already developed products with on-chip flash memory within the H8S series of high-performance, low- power-consumption microcomputers, Hitachi has now completed commercial development of the H8S/2633F with 256-kbyte on-chip flash memory to meet the need for even larger programs.

The H8S series offers enhanced performance based on the original architecture of Hitachi's H8 series, and currently includes the H8S/2655 series designed to meet the need for comprehensive peripheral functions, the H8S /2357 series with 128-kbyte on-chip flash memory to meet the demand for this kind of memory, and the H8S/2237 series provided with an on-chip 32 kHz oscillator in response to the demand for lower power consumption.

Recently, there has been a growing demand for microcomputers offering even larger on-chip flash memory and a greater variety of peripheral functions, together with low power consumption.

The newly developed H8S/2633F, the first product in the H8S series to employ a 0.35 micrometers process, features an H8S CPU core-in the top performance class for a 16-bit microcomputer-plus 256-kbyte on-chip flash memory, and is capable of single-cycle-access operation at the maximum operating frequency of 25 MHz. In addition to total erasure, the flash memory can be erased and programmed in 12 large and small block units to provide for adjustment data programming when the system is shipped. 16 kB on-chip RAM is also provided, a sufficiently large capacity to meet most needs.

In the continuing pursuit of low power consumption, the power supply voltage for the CPU and other internal logic circuitry is 3.0 to 3.6 V, while the power supply voltage of the peripheral I/O pins is 4.5 to 5.5 V, enabling existing peripheral circuits to be used, and so minimizing the amount of system reconstruction required when using the H8S/ 2633F. An on-chip PLL oscillation circuit^*2 enables a frequency multiplication factor of 4, 2, or 1 to be set by software, and used in conjunction with medium-speed mode, offers fine control of power consumption. In addition, a 32 kHz oscillator is provided as a subclock, enabling the H 8S/2633F to be used in battery-operated portable devices.

Peripheral functions include a bus controller equipped with a burst ROM interface and DRAM interface, a 4-channel DMA controller, a DTC^*3 equivalent to a maximum 85-channel DMA controller, a 5-channel serial communication interface, various timers, an A/D converter, D/A converter, and IrDA (Ver. 1.0). A 2-channel I²C^*4 bus interface can also be selected as an option. The H8S/2633F is available in two different packages: a 128-pin QFP (14 mm x 20 mm) plus a space-saving thin-type 120-pin TQFP (14 mm x 14 mm).

Two other F-ZTAT microcomputers with 256-kbyte on-chip flash memory were also developed concurrently with the H8S/2633F: the H8S/2338F and H8S/2238F. The H8S/2338F is an H8S/2357 series version with expanded I/O functions available in a 144-pin package, ideal for system control in OA products, while the H8S/2238F is an H8S/2237 series F-ZTAT^TMversion available in a 100-pin package, featuring low power consumption and low noise characteristics that make it ideal for use in products such as cellular phones and VCR cameras. The H8S/2633F, H8S/2338F, and H8S/2238F offer a choice of microcomputers with 256-kbyte on-chip flash memory in a variety of packages to suit a wide range of needs.

F-ZTAT (Flexible Zero Turn-Around Time) is a trademark of Hitachi, Ltd.

2.

PLL oscillation circuit: Phase-locked loop oscillation circuit

3.

DTC (data transfer controller): The DTC is started by an interrupt, and can perform data transfer instead of the CPU. Transfer information is located in on-chip RAM, enabling a greater number of channels to be used.

Features

1.

0.35 micrometers process, large on-chip memory

The H8S/2633F has 256-kbyte ROM and 16-kbyte RAM on-chip, placing it in the industry's top rank for a 16-bit microcomputer.

Programming and erasing can be performed using a single power supply.

2.

Low noise and low power consumption achieved through provision of on-chip PLL oscillation circuit and 32 kHz oscillation circuit

First H8S series model to incorporate a x 4 PLL oscillation circuit, achieving low noise emission.

On-chip 32 kHz oscillation circuit provides power consumption of the order of microamperes.

Efficient reduction of system power consumption achieved through the provision of various power-down modes, including medium-speed mode and module stop mode.

3.

Variety of peripheral circuits provided through use of 0.35 micrometers process

Use of a 0.35 micrometers process enables a wide variety of peripheral modules to be incorporated, including a 4-channel D/A converter, 5-channel UART, and 4-channel 14-bit PWM, to meet the needs of various applications.

While the core power supply voltage is 3.0 to 3.6 V, the pin voltage can be set to 5 V +/- 10%, making major replacement of existing system components unnecessary.

4.

High-speed operation

25 MHz operating frequency - the highest performance in the H8S series.

5.

Comprehensive on-chip peripheral functions

In addition to a 4-channel DMA controller, an 85-channel-equivalent data transfer controller is provided. A powerful 5-channel interface is also incorporated, and a 2-channel I²C bus interface can be selected as an option.

Development Environment
The existing H8 series C compiler, assembler, linkage editor, librarian, simulators, debuggers, etc., can be used asthe user software development environment on widely used personal computers and workstations. In addition, a variety of emulators, including the E6000 realtime simulator, are available as hardware support tools.
