Hitachi Europe has available a new series of 16 bit microcontrollers featuring 32 KB on-chip RAM - the first in the industry to do so. The series includes two ROM-less devices and one 384 KB Flash derivative, each combined with 32 KB fast SRAM. The devices are part of Hitachi's H8S microcontroller family, offering high 16 bit performance and significant on-chip memory and peripheral resources.

The series comprises of the H8S/2329F with 384 KB on-chip Flash (3,3 V/25 MHz), the ROM-less H8S/2324 (3,3 V/25 MHz) and the ROM-less H8S/2394 (5 V/20 MHz). At 25 MHz these devices offer approximately 12 MIPS Dhrystone, if executing from on-chip memory. The new chips are almost pin-compatible with the existing H8S/2357F, H8S/2350 and 2532 devices, all popular ROM-less and Flash devices.

Each device in the series offers the same peripheral set. This includes a DMA controller with four channels and a data transfer controller (DTC), which is a popular and more flexible versatile pseudo DMA. A bus state controller (BSC) divides the 16 MB memory space into eight areas. A number of parameters can be programmed into each of these to allow glueless access to numerous external memories and peripherals.

The H8S/2394 is supported by Hitachi's EVB2357F evaluation board for evaluation purposes and by the E6000 emulator-kit S6P-2655, which comes with everything needed, including a C Compiler. The H8S/2324 and H8S/2329F are supported by Hitachi's new E6000 emulator kit S6-2339 and by Lauterbach's Trace32-FIRE.
