An enhanced version of Hitachi's popular 5.6 inch 1/4 VGA monochrome display is now available for use in industrial instrumentation and communications equipment.
Highest density for 32Mbit synchronous SRAMs
Three new 32Mbit synchronous SRAMs that give the highest density available in a single package are being introduced by design-in specialist GD Technik.
Kim Allen, GD Technik's product marketing manager said: "Hitachi's H8S 16-bit microcontroller range has become established as one of the market's leading solutions.
The addition of the H8S/2310, H8S/2311 and H8S/2312 strengthens the range's appeal, offering full 16bit performance at 8bit microcontroller prices, enabling engineers to find the ideal match for a host of applications covering industrial, consumer, office automation and telecommunications".
The H8S/2310 with 2Kbyte RAM and the H8S/2312 with 8Kbyte RAM are both ROMless devices, while the H8S/2311 2Kbyte RAM version boasts 32Kbyte mask-ROM.
The devices operate at a frequency of 25MHz at 3.3V, providing high-speed performance of 12MIPS Dhrystone.
At a clock speed of 2MHz, power consumption is less than 10mA increasing to just 50mA at full speed.
Power consumption can be further improved by clock gearing for the bus masters, a module stop mode to turn off unused modules, together with a standby mode and a sleep mode.
A range of on-chip peripherals increases system performance by reducing the CPU's workload.
These include a data transfer controller (DTC), which serves a DMA type function and provides autonomously all peripherals and memory data transfer tasks, allowing the CPU to concentrate on its main activities.
The devices also feature a 16bit timer pulse unit (TPU), which supports cascading to form two 32bit timers.
It can also generate up to 15 PWM signals, and trigger the DTC and the analogue-digital convertor.
Other peripherals include: two extra 8bit timers to support low power operation, a watchdog timer; two serial ports (USARTs with additional support for a subset of ISO7816-3); an eight channel 10bit ADC; a two-channel 8bit DAC; and up to 71 I/O ports.
The new devices are available in TQFP only.
GD Technik provides the complete range of Hitachi development tools including its new E6000 emulator, the E62339, and Lauterbach's Trace 32-FIRE emulator.
