SuperH RISC processor powers frugal SBC
Hitex Automation has developed a high-performance single board computer based on the SH7727 microprocessor from Hitachi
The device has been developed for the EPOS (electronic point of sales) market and is suited to many other consumer and industrial applications such as plasma displays, factory automation and security systems.
Key features of the H8S/2377F include nine highly functional timers, three direct memory access controller (DMA) or DMA-like functions, five serial ports, a 16-channel 10bit A/D convertor, a six-channel 8bit D/A convertor and up to 113 I/O lines.
It also offers on-chip-debug support, which together with the embedded Flash memory facilitates convenient, low cost and quick debugging using the same device that is used in production.
The H8S/2377RF version of the microcontroller also includes an SDRAM interface, which is an unusual feature for a 16bit device.
The H8S/2377F operates at 3.3V/33MHz and delivers approximately 15MIPS dhrystone at that speed, enough to quickly calculate RSA encryption algorithms.

More memory for smart card controller
A new low-power high-memory-capacity 16bit microcontroller will enable the implementation of multiple large applications in one smart card
It typically consumes only 80mA and has several low power modes to reduce this consumption further where possible.
The device has 384Kbyte of embedded, full-speed Flash memory and 24Kbyte RAM.
There is also a low-cost mask ROM version offering 256Kbyte ROM and 16Kbyte RAM, which is ideal to implement STIP (Small Terminal Interoperability Platform) with JEFF, standards used frequently in EPOS terminals.
The five serial ports on the H8S/2377F support async, sync, multimaster, IrDA, I2C and a subset of ISO7816-3 smartcard interfaces.
The high number of serial ports, which all support ISO7816-3, is useful for EPOS systems, which often have to connect to up to four SAM (secure application modules), one per card issuer.
Other peripherals on the device include a six-channel 16bit timer module with up to 16 input capture or output compare units, a two-channel 8bit timer module and a watchdog timer.
It has one standard DMA, one specialised for very fast external bus transfers and a third slightly slower but very versatile data transfer controller (DTC) that can serve most peripherals.
The device also has a programmable pulse generator module (PPG), that can drive a stream of digital data patterns onto up to 16 pins under timer control, thus avoiding the jitter that would be associated with interrupt services.
This is useful to drive stepper motors (for example, in motorised card readers or bank note dispensers), but can also be used to drive LCD modules without the need for an additional external LCD timing controller.
The H8S/2377F is available in an 144-pin quad flatpack (QFP) and in either conventional or lead-free technology.
It is supported by Hitachi's popular E6000 emulator and by Lauterbach's Trace32-ICD on-chip-debug tool.
An evaluation board is available under the part name EDK2377, and can directly connect to Trace32-ICD as a dummy target before customers have their own PCB.
