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)
