The H8 Value Series of 16-bit microcontrollers consists of economical versions of the existing H8 devices. Suitable for GPS receivers, emission text equipment, label printers, touch-screen controllers, bar-code scanners, point-of-sale equipment, and security systems, the series is targeted at cost-sensitive products that require larger flash memory and more CPU performance than found in traditional 8-bit microcontrollers.
The Value Series processors feature 25MHz operating frequency with a minimum instruction execution time of 40 nanoseconds for the H8S series devices and 80ns for the H8/300H series devices, according to company claims. These devices have 4KB or 8KB of RAM and 128KB of ROM (flash or mask type). Devices are offered in operating voltages ranging from 3V to 3.6V for the H8S and H8/300H devices to 4.5V to 5.5V for some of the H8/300H s. The H8 Value Series microcontrollers include an 85-channel data transfer controller and four-channel direct memory access controller. These functions off-load the CPU when data is obtained from and sent to external memory, allowing higher system throughput and performance, according to the company. Other on-chip resources include timers (8-bit, 16-bit, and watchdog), a 16-bit programmable pulse generator, data converters (8- or 12-channel 10-bit ADC and 2- or 4-channel 8-bit DAC), two or three channels of serial communication interface, and a smart card interface. The devices are available in 100-, 128- and 144-pin QFP packages.
H8 Value Series microcontrollers are available now.
