MCUs have a huge 32Kbyte of RAM on-chip
Hitachi Europe has announced the immediate availability of a new series of 16bit microcontrollers featuring 32Kbyte on-chip RAM - the first in the industry to do so.
Most integrated GSM RF transceiver so far
Hitachi has launched its most integrated GSM RF transceiver solution to date.
The new device caters for Hitachi's extensive customer base, and is designed for applications that require greater CPU performance and software compatibility.
The H8S/2676F features a general purpose, register architecture H8S CPU, with eight 32bit wide registers, instruction prefetch and a 16Mbyte linear address range.
It also has a hardware multiply-accumulate unit (MAC), which accelerates DSP-type algorithms by a factor of between two and three, when compared with H8S derivatives without MAC.
Using MAC, a 16 x 16bit multiply can be executed in 90ns at 33MHz.
The device offers 256Kbyte embedded full-speed Flash and 8Kbyte RAM.
Its comprehensive peripheral set includes direct memory access (DMA), data transfer controller (DTC, a versatile pseudo DMA), a highly sophisticated six-channel 16bit timer unit (TPU) with up to 16 input capture and output compare, 16 channel real time outputs (PPG) and three channel USARTs.
Also included on the device are a 12-channel 10bit ADC, a four channel 8bit DAC and up to 115 I/O lines, some of which feature programmable pull-up and open drain, as well as schmitt trigger and interrupt capability.
All USARTs provide for asynchronous, synchronous, multiprocessor and a subset of ISO7816-3 communication.
One USART also has an IrDA mode.
Clock generation is via a PLL circuit to minimise the power consumption of the clock generation and to ease radiation problems.
The device also has several low power features like clock gearing and standby modes.
Unused peripherals and the CPU can be shut down under software control.
The H8S/2676F is supported by Hitachi's E6000 emulator and by Lauterbach's Trace32-FIRE (under development).
The H8S/2676F comes in a 144-pin QFP and is available immediately.
Mask ROM versions and an 8Kbyte RAM ROMless version are also available.
