Overview
MSP430F5658IPZR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller with USB 2.0 interface, 384 KB flash, 32 KB + 2 KB RAM, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, and integrated LCD driver for up to 160 segments - deployed in battery-powered sensor nodes and portable meters.
For engineers reviewing the MSP430F5658IPZR datasheet, MSP430F5658IPZR pinout, MSP430F5658IPZR application, or MSP430F5658IPZR equivalent, this page delivers verified technical context, exact package mapping (LQFP-100), validated pin functions, real low-power mode currents (2.0 µA in LPM3), USB PHY integration, and two confirmed alternative MCUs for design continuity.
Technical Context
The MSP430F5658IPZR implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling 3 µs wake-up from standby (LPM3). Its unified clock system integrates FLL stabilization, VLO/REFO internal sources, XT1 (32-kHz crystal), and XT2 (up to 32-MHz crystal) for flexible timing control across active and low-power modes.
Peripherals include three USCI modules (USCI_A0–A2 supporting UART/IrDA/SPI; USCI_B0–B2 supporting I²C/SPI), six-channel DMA, RTC_B with battery backup, hardware multiplier (MPY32), CRC16 engine, and memory integrity detection (MID). USB functionality uses an integrated PHY, PLL, 3.3-V/1.8-V power system, and eight IN/OUT endpoints - all operating without external voltage translation.
