Product details
Overview
MSP430F5659IZCAT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 512 KB flash, 64 KB + 2 KB RAM, USB 2.0 full-speed interface, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, and integrated LCD driver for up to 160 segments. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and portable instrumentation requiring rapid wake-up (3 µs from LPM3) and RTC-backed operation.
For engineers reviewing the MSP430F5659IZCAT datasheet, MSP430F5659IZCAT pinout, MSP430F5659IZCAT application, or MSP430F5659IZCAT equivalent, key selection criteria include USB integration without external PHY, ultra-low standby current (2.0 µA at 3.0 V in LPM3), 74 GPIOs with flexible peripheral mapping, and support for real-time clock with crystal backup in shutdown mode (LPM3.5).
Technical Context
The MSP430F5659IZCAT implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL, VLO, REFO, XT1 (32 kHz), and XT2 (up to 32 MHz), enabling precise frequency stabilization and dynamic low-power mode transitions.
Peripheral integration includes three USCI modules (USCI_A0–A2 for UART/IrDA/SPI; USCI_B0–B2 for I²C/SPI), six-channel DMA, RTC_B with alarm and battery backup, CRC16 engine, and memory integrity detection (MID). Unlike MSP430F665x variants, it omits integrated LCD_B but retains USB-PHY, USB-PLL, and dual 3.3-V/1.8-V USB power system.

FAQ
What is the maximum system clock frequency supported by the MSP430F5659IZCAT?
The MSP430F5659IZCAT supports a maximum system clock frequency of 20 MHz, derived from its integrated digitally controlled oscillator (DCO) or external high-frequency crystal (XT2) up to 32 MHz. This frequency enables real-time USB packet handling, 200 ksps ADC sampling, and deterministic execution of control algorithms within tight timing budgets.
Does the MSP430F5659IZCAT include an integrated LCD driver?
No, the MSP430F5659IZCAT does not include an integrated LCD driver. While the broader MSP430F565x family shares many features with LCD-capable variants like MSP430F6659, the MSP430F5659IZCAT specifically omits the LCD_B module. Its functional block diagram and device comparison table confirm absence of LCD segment drive capability.
What USB power supply voltages does the MSP430F5659IZCAT generate internally?
The MSP430F5659IZCAT integrates a dual-voltage USB power system generating both 3.3 V and 1.8 V supplies directly from the main DVCC rail. These internally regulated voltages power the USB PHY, PLL, and endpoint buffers - eliminating need for external LDOs or charge pumps in USB-enabled designs.
How many capture/compare registers are available across the Timer_A modules in the MSP430F5659IZCAT?
The MSP430F5659IZCAT includes three Timer_A instances: TA0 with five capture/compare registers, and TA1 and TA2 each with three capture/compare registers. This configuration supports simultaneous PWM generation, input capture for encoder signals, and interval timing - all with independent clock sources and interrupt vectors.
Is the MSP430F5659IZCAT pin-compatible with the MSP430F6659IZCA?
No, the MSP430F5659IZCAT is not pin-compatible with the MSP430F6659IZCA. Although both use nFBGA-113 packages and share many peripheral functions, their pin mappings differ significantly - particularly for USB, LCD, and certain I/O multiplexing. The device comparison table and signal descriptions confirm distinct terminal assignments requiring separate PCB layouts.
