Product details
Overview
MSP430F5659IZQWT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 512 KB flash, 64 KB + 2 KB RAM, integrated USB 2.0 PHY, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, LCD driver (160 segments), and four 16-bit timers - deployed in portable sensor systems and battery-powered human-interface devices.
For engineers reviewing the MSP430F5659IZQWT datasheet, MSP430F5659IZQWT pinout, MSP430F5659IZQWT application, or MSP430F5659IZQWT equivalent, key selection criteria include USB integration without external transceiver, LPM3.5 RTC operation at 1.1 µA, 3 µs wake-up from standby, and MicroStar Junior BGA (113-pin) packaging for space-constrained designs.
Technical Context
The MSP430F5659IZQWT implements a 16-bit RISC CPU with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL stabilization, VLO/REFO internal sources, XT1 (32-kHz crystal), and XT2 (up to 32 MHz), enabling precise timing across ultra-low-power modes.
Power management includes a programmable LDO core regulator, supply voltage supervisor (SVS), brownout reset (BOR), and five low-power modes (LPM0–LPM4.5). The device supports full RAM retention in LPM3 (2.0 µA @ 3.0 V) and RTC-active shutdown in LPM3.5 (1.1 µA @ 3.0 V).
Key Specifications
