512K flash micro allows greater on-chip software functionality

14 February 2001 DSP, Micros & Memory

Hitachi has announced availability of the H8/3052F, a 16 bit microcontroller based on the H8/300H CPU core. The device features a large on-chip flash memory of 512 KB which allows the integration of communication functions with motor control and industrial applications. Until now this has required the use of an additional microcontroller.

The H8/3052F is ideally suited as an upgrade for the popular H8/3048F. It offers four times the flash memory (512 KB) and double the RAM (8 KB) of that device, together with an increase in clock speed from 16 to 18 MHz, further enhancing performance. This enables Hitachi to provide its extensive H8/3048F customer base with an essential upgrade for next generation products. The H8/3052F also features virtually the same pin-out and the same set of peripherals as the older device, allowing for the easy redesign of H8/3048F-based systems.

The H8/3052F effectively handles AC motor PWM generation through its advanced ITU timer unit, which features PWM modes specifically designed for that task. It operates from 5 V, yet consumes only 31 mA (typical) at the full speed of 18 MHz.

Other peripherals include a 4-channel DMA, two serial ports, an 8-channel 10 bit ADC, a 2-channel 8 bit DAC and a watchdog timer. A proportion of the 70 I/O and nine input-only ports feature programmable pull-up resistors, 10 mA drive capability and schmitt trigger characteristics, as well as interrupt functionality including NMI.

The device is available immediately in a FP-100B package with emulator support. An evaluation board is planned for release in early 2001.
