Product List

SM8954BW40PP,

SM8954BW44JP,

SM8954BW44QP,

Features



Main Flash ROM 16KB.

Working voltage 2.4V~5.5V.

4.5V ~ 5.5V runs up to 40MHz.

2.4V ~ 3.6V runs up to 24MHz.

General 8052 family compatible with 12

clocks in one machine cycle.

Description



The SM8954B series product is an 8 - bit single chip

micro controller with 16KB flash & 1KB SRAM

embedded.



256 bytes SRAM as standard 8052.

On-chip 768 bytes expanded RAM.

16-bit Data Pointers (DPTR).

One serial peripheral interfaces in full duplex

mode (UART).

SM8954B is a versatile and cost effective controller for

those applications which demand up to 36 I/O pins, or

applications which need up to 16K byte flash memory

either for program or for data or mixed.

Synchronous mode, fixed baud rate.

8-bit UART mode, variable baud rate.

9-bit UART mode, fixed baud rate.

9-bit UART mode, variable baud rate.

To program the on-chip flash memory, a commercial

writer is available to do it in parallel programming

method.



Three 16-bit Timer/Counters (Timer 0, 1, 2).

One watch dog timer (WDT).

One IIC interface (Master / Slave mode).

Two 8-bit/5-bit configurable PWM output

channels.
