UNIVERSAL SYNCHRONOUS ASYNCHRONOUS RECEIVER TRANSMITTER

GENERAL DESCRIPTION

The MSM82C51A-2 is a USART (Universal Synchronous Asynchronous Receiver Transmitter)

for serial data communication.

As a peripheral device of a microcomputer system, the MSM82C51A-2 receives parallel data

from the CPU and transmits serial data after conversion. This device also receives serial data

from the outside and transmits parallel data to the CPU after conversion.

The MSM82C51A-2 configures a fully static circuit using silicon gate CMOS technology.

Therefore, it operates on extremely low power at 100

(max) of standby current by

suspending all operations.

FEATURES

• Wide power supply voltage range from 3 V to 6 V

• Wide temperature range from –40°C to 85°C

• Synchronous communication upto 64 Kbaud

• Asynchronous communication upto 38.4 Kbaud

• Transmitting/receiving operations under double buffered configuration.

• Error detection (parity, overrun and framing)

• 28-pin Plastic DIP (DIP28-P-600-2.54): (Product name: MSM82C51A-2RS)

• 28-pin Plastic QFJ (QFJ28-P-S450-1.27): (Product name: MSM82C51A-2JS)

• 32-pin Plastic SSOP(SSOP32-P-430-1.00-K): (Product name: MSM82C51A-2GS-K)
