SLAS491A − AUGUST 2005 − REVISED OCTOBER 2005
USI (MSP430x20x2 and MSP430x20x3 only)
The universal serial interface (USI) module is used for serial data communication and provides the basic
hardware for synchronous communication protocols like SPI and I2C.
ADC10 (MSP430x20x2 only)
The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR
core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion
result handling allowing ADC samples to be converted and stored without any CPU intervention.
SD16_A (MSP430x20x3 only)
The SD16_A module supports 16-bit analog-to-digital conversions. The module implements a 16-bit
sigma-delta core and reference generator. In addition to external analog inputs, an internal V_CC sense and
temperature sensor are also available.
