Product details
Overview
MSP430L092SPWR from Texas Instruments is an ultra-low-voltage (0.9–1.65 V) 16-bit RISC microcontroller with integrated 8-bit ADC, 8-bit DAC, programmable comparator, and dual 16-bit timers (Timer0_A3 and Timer1_A3), designed for single-cell battery-powered measurement systems requiring full analog signal chain capability.
For engineers reviewing the MSP430L092SPWR datasheet, MSP430L092SPWR pinout, MSP430L092SPWR application, or MSP430L092SPWR equivalent, key selection criteria include ULV operation down to 0.9 V, 2 kB loader ROM with SPI/I2C boot support, 2 kB RAM (1792 + 128 + 96 bytes lockable), 4-µs wake-up from LPM4, and JTAG debug interface compatibility with MSP430x09x family toolchains.
Technical Context
The MSP430L092SPWR implements a Compact Clock System (CCS) with internal 20-kHz LF-OSC and trimmable 1-MHz HF-OSC, supporting ACLK, MCLK, and SMCLK generation without external crystals. Its analog pool (A-Pool) dynamically configures shared hardware resources for ADC, DAC, comparator, and supply voltage monitoring functions using a unified register set and voltage divider network.
It features two independent 16-bit timer modules-Timer0_A3 and Timer1_A3-each with three capture/compare registers, PWM output capability on all I/O pins, and interrupt generation on overflow and compare events. The device uses a 14-pin TSSOP (PW) package with 7 GPIO on Port P1 and 4 GPIO on Port P2, all supporting edge-selectable interrupts and programmable pullup/pulldown.

FAQ
What is the minimum operating voltage for the MSP430L092SPWR?
The MSP430L092SPWR operates down to 0.9 V in active mode at 1 MHz and supports full functionality-including RAM retention and analog peripherals-at this ultra-low supply voltage. Its ULV brownout circuit and dedicated retention voltage ensure reliable operation even as primary batteries discharge below 1.0 V, making it ideal for single-cell alkaline or lithium coin cell applications where extended runtime is essential.
Does the MSP430L092SPWR support in-system programming via JTAG?
Yes, the MSP430L092SPWR includes a full four-wire JTAG interface compliant with IEEE 1149.1, enabling in-system programming, real-time debugging, and boundary-scan testing. The JTAG pins (TCK, TMS, TDI, TDO) are multiplexed on Port P2.0–P2.3 and retain full debug functionality regardless of port configuration, allowing firmware updates and diagnostics without removing the device from the PCB.
How does the analog pool (A-Pool) function in the MSP430L092SPWR?
The A-Pool in the MSP430L092SPWR is a shared analog hardware block configurable via APCTL and APOMR registers to operate as an 8-bit ADC, 8-bit DAC, programmable comparator, or supply voltage monitor. It uses internal voltage dividers and reference sources to support multiple analog functions without dedicated silicon per function-reducing power, die size, and cost while maintaining signal chain accuracy for sensor interface applications.
What memory resources are available on the MSP430L092SPWR?
The MSP430L092SPWR provides 2 kB of loader ROM (for secure boot), 2 kB of RAM organized as 1792 B application RAM + 128 B boot code RAM + 96 B calibration RAM (all lockable), and no user-programmable Flash or EEPROM. Firmware is loaded into RAM at boot from external SPI/I2C memory, enabling field-upgradable code while preserving data integrity through power-loss events.
Can the MSP430L092SPWR generate PWM signals on all I/O pins?
Yes, the MSP430L092SPWR supports PWM output on all 11 I/O pins (P1.0–P1.6 and P2.0–P2.3) through Timer0_A3 and Timer1_A3 modules. Each timer has three capture/compare registers capable of generating independent PWM waveforms with programmable period and duty cycle, enabling simultaneous control of multiple actuators, LED drivers, or motor phases without additional external hardware.
