Semiconductor MSM6404A/6404VS
High speed and High performance 4-Bit Microcontroller
This MSM6404A/6404VS version: Sep. 1998 Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM6404A microcontroller is a low-power device implemented in complementary metaloxide semiconductor technology. The MSM6404A is optimized for high-speed processing and complicated-control applications. The MSM6404VS is a CMOS 4-bit microcontroller that employs an external EPROM using a piggy-back package in place of the program memory (ROM) internal to the MSM6404A. The MSM6404VS can be used for program development verification because the programs can be modified by programming an external EPROM 2732 equivalent or 2764A equivalent.

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
