Japan's Renesas Technology Inc., the new joint IC venture between Hitachi Ltd. and Mitsubishi Electric Corp., introduced a 16-bit microcontroller line for low-cost applications.
The H8 Value Series of controllers are ideal for GPS receivers, emission text equipment, label printers, touch screen controllers, bar code scanners, point-of-sale equipment and security systems and other products, according to the Tokyo-based company.
The device achieves a 25MHz operating frequency, with a minimum instruction execution time of 40ns for the H8S series and 80ns for the H8/300H series. The devices have 4- or 8Kbytes of RAM and 128KBytes of ROM.
Renesas also offers devices in various operating voltage ranges, from 3- to 3.6V for the H8S and H8/300H devices and 4.5- 5.5V for some of the H8/300H MCUs.
The H8 Value Series MCUs include a fast, 85-channel data transfer controller (DTC) and 4-channel direct memory access controller (DMAC). These functions off-load the central processing unit (CPU) when data is obtained from and sent to external memory, allowing higher system throughput and performance, the company said.
Other on-chip resources include timers (8-bit, 16-bit and watchdog), 16-bit programmable pulse generator (PPG), data converters (8- or 12-channel 10-bit ADC and 2- or 4-channel 8-bit DAC), 2 or 3 channels of serial communication interface, and a smart card interface.
The devices are available in 100-, 128-, and 144-pin QFP packages. Prices depend upon the model.
