Page 2: Introduction
Introduction www.ti.com 1 Introduction The TRS3221RGTEVM is an evaluation module for the TRS3221RGT and TRSF3221RGT devices, normal and high-speed RS-232 transceivers. Features • Interface with MCUs or processor from 3 V up to 5.5 V • High-speed RS-232 communication, up to 1 Mbps •... -
Page 3: Test Setup
VCC is supplied with external power; 3.3 V or 5 V is recommended. The GND header pins are the ground connection for the TRS3221RGTEVM. The DB9 connector mates with a personal computer's RS-232 port or a USB to RS-232 adapter. For initial testing, external wires can be added. The ideal usage involves connecting the terminal block data and control lines to a system that has an UART (Universal asynchronous receiver/ transmitter) onboard. -
Page 4: Schematic And Layout
The TRS3221RGTEVM has simple connections to all necessary pins of the TRS3221RGT transceiver device, and jumpers where necessary to provide flexibility for device. The TRS3221RGTEVM provides test points for all RS-232 (TX1, RX1) and logic (TX2, RX2) communication lines. Additionally test points of GND, VCC, and charge pump output voltage are available for probing and evaluation. - Page 5 VALID RIN RS-232 FORCEON FORCEOFF DOUT LEVEL Powered off Normal operation with automatic power down disabled Normal operation with automatic power down enabled SLLU328 – DECEMBER 2020 TRS3221 EVM User's Guide Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated...
