The new H8/3052F 16-bit microcontroller from Hitachi features a large on-chip flash memory of 512Kbyte which allows the integration of communication with motor control and industrial applications
Specialist distributor GD Technik offers the new H8/3052F 16-bit microcontroller from Hitachi.
The device is based on Hitachi's H8/300H CPU core and features a large on-chip flash memory of 512Kbyte.
This 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 reinforces Hitachi's position as a dominant supplier in the 16-bit microcontroller with on-chip flash market.
The large flash memory of the H8/3052F coupled with 8Kbyte of RAM and a clock speed of 18Mhz makes the device an ideal upgrade for the H8/3048F, one of Europe's most popular current microcontrollers.
Next generation product design can easily incorporate the new, significantly more powerful device, as the pin-outs are virtually the same and an identical set of peripherals are used.
Housed in an FP-100B package, the H8/3052F operates from 5V and consumes only 31mA at the full 18MHz clock speed.
AC motor PWM generation is handled through its advanced ITU timer unit, which features PWM modes specifically designed for that task.
There are numerous other peripherals on the device, these include; a four channel DMA, two serial ports, an eight channel 10-bit ADC, a two 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, 10mA drive capability and Schmitt trigger characteristics, as well as interrupt functionality including NMI.
