uClinux supports new Hitachi H8S microcontroller
Dec. 10, 2002

San Jose, CA -- (press release excerpt) -- Hitachi Semiconductor announced the H8S/2674R microcontroller, a 33 Megahertz (MHz) 16-bit device with a built-in SDRAM memory interface. The device is suitable for office automation products such as printers, scanners and fax machines, network systems like high-speed buffer products for content download from the Internet and low-end multimedia and handheld devices.

The H8S/2674R has an on-chip 32KB SRAM to execute time-critical routines, as well as a hardware multiply-accumulate (MAC) unit that enables the MCU to run DSP-type software applications up to three
times faster than other 33MHz H8S chips without hardware MACs. For example, using the MAC, the H8S/2674R running at 33MHz executes a 16x16-bit multiplication operation in only 120 nanoseconds.

The H8S/2674R integrates many peripheral functions, including a DMA controller, data transfer controller (DTC), 6-channel 16-bit timer pulse unit, programmable pulse generator, watchdog timer, 12-channel 10-bit A-to-D converter, 4-channel 8-bit DAC, clock pulse generator with phase-locked-loop, 3-channel serial communication interface with IrDA and serial bus capabilities, and up to 115 I/O lines. For reduced system power dissipation, the H8S/2674R offers six
power down modes,

Extensive software/hardware development tools for the H8S/2674R are available from Hitachi and third-party suppliers. To ensure a flexible and reliable design environment, Hitachi is offering a low-cost Evaluation Design Operating System Kit (EDOSK), available for $199 through Hitachi distributors, which includes an H8S/2674R development board with 4 MB of on-board flash and 8 MB of SDRAM memory, an Ethernet interface, boot loader software stored in boot flash, plus operating system support from several vendors.

uClinux support for the H8S/2674R is offered by Arizona Cooperative Power.

Further details on the new Hitachi H8S/2674R microcontroller are available here.
