MSM85C154HVS

MSM83C154S Piggy Back

GENERAL DESCRIPTION

The MSM85C154HVS is an 8-bit microcontroller that has been developed assuming that it is used
for evaluation of programs of MSM83C154S. ES (Engineering Sample) only.

FEATURES

• Operating range
Operating frequency : 1 to 22 MHz (16 to 22 MHz is recommended

for program development)

Operating voltage : 4.75 to 5.25 V (Use MSM85C154VS for 1 to 16

MHz)

Operating temperature : Room temperature

• Fully static circuit

• On-chip program memory : 16K ¥ 8-bit ROM (EPROM)

• On-chip data memory : 256 ¥ 8-bit RAM

• External program memory address space : 64 Kbytes

• External data memory address space : 64 Kbytes

• I/O port

(Port 1, 2, 3, impedance programmable) : 4 ports ¥ 8 bits

• 16-bit timer/counters : 3

• Multifunctional serial port : I/O Expansion mode

: UART mode (featuring error detection)

• 6-source 2-priority level

Interrupt and multi-level
Interrupt available by programming IP and IE registers

• Memory-mapped special function registers

• Bit addressable data memory and SFRs

• Minimum instruction cycle : 545 ns @ 22 MHz operation

• "Multiply"/"divide" instruction cycle : 2.18 ms @ 22 MHz operation

• Standby functions : Power-down mode (oscillator stop)

Activated by software or hardware; provid­ing ports with floating or active status
The software power-down stet mode is ter­minated by interrupt signal enabling execu­tion from the interrupted address.

• Package
40-pin ceramic Piggyback (ADIP40-C-600-2.54) (Product name: MSM85C154HVS)

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).
