Hitachi has released its first microcontroller to incorporate the company's 4th generation Flash technology. The H8/3069F is manufactured using a 0,18 mm process and is the company's most cost-effective 512 KB Flash microcontroller. The enhanced Flash offers faster programming, on-chip firmware for simplified handling and a user boot program area. The device is aimed at highly sophisticated, but cost-critical industrial and consumer applications such as metering and white goods.

The H8/3069F is the flagship of Hitachi's H8/306x series and features the largest on-chip memory capacity in the economical H8/300H 16-bit microcontroller family by combining 512 KB Flash with 16 KB SRAM on-chip. At 2,5 s for 128 KB, the Flash write speed is approximately three times faster than current Hitachi products.

The on-chip firmware simplifies handling and shortens development time by eliminating the need for a user-written control program and making software more reliable and future-proof. The firmware consists of protected routines, which can be called from within a user's application code for writing and erasing to the Flash.

The H8/3069F provides a small additional protected Flash area of 8 KB, enabling customers to create their own boot program, store monitor firmware or hide encryption software. Program code stored in this area can be executed after reset simply by selection via mode pins. The guaranteed number of Flash write/erase cycles has been improved.

The new device has a comprehensive peripheral set including three 16-bit timers, four 8-bit timers and a watchdog timer. It also boasts an eight-channel 10-bit analog/digital converter, a four-channel DMA controller, 79 I/O channels and a three-channel serial interface (USART) with a smartcard interface option.

The microcontroller is supported by an evaluation kit and the realtime emulators E63064B and Lauterbach Trace32-Fire. The H8/3069F is available in a 100-pin QFP or TQFP.
