Features

The core of each product in the H8SX/1668R Group and H8SX/1668M Group of CISC (complex

instruction set computer) microcontrollers is an H8SX CPU, which has an internal 32-bit

architecture. The H8SX CPU provides upward-compatibility with the CPUs of other Renesas

Technology-original microcontrollers; H8/300, H8/300H, and H8S.

As peripheral functions, each LSI of the Group includes a DMA controller and an EXDMA

controller which enable high-speed data transfer, and a bus-state controller, which enables direct

connection to different kinds of memory. The LSI of the Group also includes serial

communications interfaces, A/D and D/A converters, and a multi-function timer that makes motor

control easy. Together, the modules realize low-cost configurations for end systems. The power

consumption of these modules is kept down dynamically by an on-chip power-management

function. The on-chip ROM is a flash memory (F-ZTAT

TM*) with a capacity of 1024 Kbytes

(H8SX/1668R, H8SX/1668M), 512 Kbytes (H8SX/1664R, H8SX/1664M), or 384 Kbytes

(H8SX/1663R, H8SX/1663M).
