Preface
Introduction
The HMCS43XX Family of 4-bit microcomputers are built around the HMCS400 CPU core,
which has a powerful architecture designed for efficient programming. All of these
microcomputers include standard on-chip peripheral functions, including a multiple input channel
A/D converter, a serial interface, and multi-function timers.
The peripheral functions are developed individually as modules, and connected using a standard
interface.
This manual describes six product series in the HMCS43XX Family: the HD404344R,
HD404394, HD404318, HD404358, HD404358R, HD404339, and HD404369 series. The
products in these series form a fine-grained product line in which products are differentiated by
their memory capacities, medium and high voltage pins, high current pins, low power modes,
normal vs. high-speed versions, and other aspects. This allows an appropriate microcomputer to be
selected for a wide range of applications.
All members of the HMCS43XX Family are available in both ROM and PROM (ZTAT™)
versions. PROM versions can be programmed freely by the user with a general purpose PROM
writer.
