Texas Instruments MSP430F4361IPZ

Overview

MSP430F4361IPZ from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller featuring 24KB+256B flash memory, 1KB RAM, integrated 160-segment LCD driver, dual 16-bit timers (Timer_A3 and Timer_B3), and USART0 with UART/SPI mode selection. It operates from 1.8 V to 3.6 V and targets battery-powered portable measurement systems requiring long runtime and on-device display.

For engineers reviewing the MSP430F4361IPZ datasheet, MSP430F4361IPZ pinout, MSP430F4361IPZ application, or MSP430F4361IPZ equivalent, key selection criteria include its 100-pin QFP package, absence of ADC12 module (per F43x1 family designation), standby wake-up time under 6 µs, and LCD segment drive capability up to 160 segments with four backplane outputs.

Technical Context

The MSP430F4361IPZ implements a 16-bit CPU with constant generators and a digitally controlled oscillator (DCO) enabling sub-6-µs wake-up from standby mode. Its peripheral set includes Timer_A3 with three capture/compare registers and Timer_B3 with three capture/compare registers plus shadow registers - optimized for precise timing control in metering and industrial sensing.

It integrates a hardware comparator, brownout detector, supply voltage supervisor with programmable level detection, and serial onboard programming without external voltage. The device lacks the ADC12 module present in non-"1" variants (e.g., MSP430F436IPZ), confirming its role in applications prioritizing LCD-driven user interface and low-power timing over analog signal acquisition.

FAQ

Does the MSP430F4361IPZ include an analog-to-digital converter?

No, the MSP430F4361IPZ does not include the ADC12 module. As a member of the "x43x1" family variant, it omits the 12-bit ADC entirely - confirmed in TI's SLAS344G datasheet footnote §. This distinguishes it from the pin-compatible MSP430F436IPZ, which retains the ADC. The MSP430F4361IPZ is intended for applications where LCD display, timing, and communication are prioritized over analog signal acquisition.

What is the maximum number of LCD segments supported by the MSP430F4361IPZ?

The MSP430F4361IPZ supports up to 160 LCD segments using a 4-backplane (COM0–COM3) configuration. This is explicitly stated in the functional block diagram (page 9) and terminal function tables (pages 11–13) of the SLAS344G datasheet. The device dedicates 40 segment outputs (S0–S39) plus additional Sxx pins across ports P2–P5 to achieve full 160-segment drive capability.

Which communication interfaces are available on the MSP430F4361IPZ?

The MSP430F4361IPZ features one USART (USART0), configurable in either asynchronous UART mode or synchronous SPI mode via software control. It does not include USART1 - a feature reserved for the MSP430x44x(1) family. UART mode supports standard serial communication (e.g., debug output or host interface), while SPI mode enables master/slave connectivity with sensors, displays, or wireless modules.

What package type and pin count does the MSP430F4361IPZ use?

The MSP430F4361IPZ uses a 100-pin plastic quad flat pack (QFP) package, designated "PZ" in TI's ordering nomenclature. This is confirmed in the "AVAILABLE OPTIONS" table (page 2) and pin diagrams for PZ-package devices (pages 4 and 7) of SLAS344G. The package has 0.5 mm lead pitch and is RoHS-compliant.

How does the power consumption of the MSP430F4361IPZ compare across operating modes?

The MSP430F4361IPZ draws 280 µA in active mode (1 MHz, 2.2 V), 1.1 µA in standby mode, and 0.1 µA in off mode with RAM retention - all specified in the absolute maximum ratings and electrical characteristics section of SLAS344G. These values reflect its ultralow-power design, enabling multi-year operation on coin cells or primary batteries in infrequently active applications.
