Product details
Overview
MSP430F123IPWR-HYD from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller featuring 8KB+256B Flash, 256B RAM, a 16-bit Timer_A with three capture/compare registers, on-chip analog comparator, and USART0 supporting UART/SPI modes. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems requiring sub-μA standby current and <6 μs wake-up.
For engineers reviewing the MSP430F123IPWR-HYD datasheet, MSP430F123IPWR-HYD pinout, MSP430F123IPWR-HYD application, or MSP430F123IPWR-HYD equivalent, key selection criteria include its 28-pin TSSOP (PW) package, LPM4 current of 0.1–0.5 μA, 16-bit timer resolution, integrated slope A/D capability via comparator, and JTAG + BSL programmability without external voltage.
Technical Context
The MSP430F123IPWR-HYD implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock module supports multiple sources: internal DCO (stabilizes in <6 μs), 32 kHz crystal, high-frequency crystal, resonator, or external clock - all configurable via BCSCTL1/2 and DCOCTL registers.
Peripheral integration includes Timer_A3 with three independent capture/compare registers (TACCR0–2), a comparator_A module usable for analog signal comparison or single-slope A/D conversion, and USART0 with dual-buffered TX/RX supporting software-selectable asynchronous UART or synchronous SPI protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 general-purpose registers and constant generators; enables highly efficient code execution and low cycle-per-instruction overhead. |
| Memory | 8KB + 256B Flash program memory and 256B RAM; supports in-system programming via JTAG or BSL UART interface. |
| Supply Voltage | 1.8 V to 3.6 V operating range; allows direct use with single-cell Li-ion, two-cell alkaline, or regulated 3.3 V rails. |
| Active Current | 200 μA at 1 MHz / 2.2 V; enables continuous sensing and processing in energy-constrained portable applications. |
| Low-Power Modes | Five software-selectable modes including LPM4 (0.1–0.5 μA); retains RAM while disabling all clocks and oscillator for maximum battery life. |
| Wake-Up Time | <6 μs from LPM3/LPM4 to active mode via DCO; critical for responsive event-driven sensor wake-up without timing jitter. |
| Timer Resolution | 16-bit Timer_A with three capture/compare registers; supports PWM generation, input capture, interval timing, and interrupt-on-compare events. |
Pinout & Package
Package: 28-pin Plastic Thin Shrink Small-Outline Package (TSSOP), suffix PW - body width 4.4 mm, lead pitch 0.65 mm, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F122IPWR | 4KB+256B Flash (vs. 8KB), otherwise identical peripheral set, pinout, and electrical specs. | Suitable where firmware size ≤4KB; no change to PCB or driver layer needed. | Select when application code footprint fits within 4KB and cost optimization is prioritized. |
| MSP430F1122IPW | 28-pin TSSOP, 4KB Flash, 256B RAM, but lacks USART0 - only Timer_A and comparator; no UART/SPI hardware. | Requires external UART IC or bit-banged serial for host communication; not drop-in for USART-dependent designs. | Choose only if serial communication is unnecessary or implemented externally; verify full peripheral compatibility before substitution. |
Compared with MSP430F122IPWR, the MSP430F123IPWR-HYD provides double Flash capacity for larger firmware or calibration data, while MSP430F1122IPW omits USART0 entirely - making it unsuitable for any design relying on hardware UART/SPI, despite matching package and core architecture.

FAQ
What is the package type and pin count of the MSP430F123IPWR-HYD?
The MSP430F123IPWR-HYD uses a 28-pin Plastic Thin Shrink Small-Outline Package (TSSOP), designated by the "PW" suffix. It measures 9.7 mm × 4.4 mm with 0.65 mm lead pitch and is RoHS-compliant. This package matches the pinout of other MSP430F12x devices in the PW variant, including identical signal assignments for P1–P3, RST/NMI, TEST, and power pins.
Does the MSP430F123IPWR-HYD support hardware UART and SPI simultaneously?
No - the MSP430F123IPWR-HYD contains a single USART0 module that can be software-configured *either* as asynchronous UART *or* synchronous SPI, but not both concurrently. The mode is selected at runtime via U0CTL register bits (SYNC=0 for UART, SYNC=1 for SPI), and pin functions (e.g., P3.4/UTXD0, P3.5/URXD0) adapt accordingly. Dual-protocol operation requires external logic or time-multiplexing.
What is the minimum supply voltage required to program the Flash memory of the MSP430F123IPWR-HYD?
The MSP430F123IPWR-HYD requires a minimum VCC of 2.7 V to perform Flash memory programming or erase operations, as specified in the recommended operating conditions. While the device operates down to 1.8 V in active or low-power modes, Flash writes below 2.7 V are not guaranteed and may result in incomplete or corrupted programming. Always ensure stable ≥2.7 V during BSL or JTAG programming sequences.
Can the MSP430F123IPWR-HYD perform analog-to-digital conversion without an external ADC?
Yes - the MSP430F123IPWR-HYD integrates a comparator_A module that supports slope-type analog-to-digital conversion. By charging a capacitor through a known current and comparing its voltage against the input signal using the comparator, the device can digitize analog values with software-timed resolution. This eliminates the need for an external ADC in low-channel-count, moderate-speed applications like resistive sensor reading.
Is the MSP430F123IPWR-HYD pin-compatible with the MSP430F122IPWR?
Yes - the MSP430F123IPWR-HYD and MSP430F122IPWR share identical 28-pin TSSOP (PW) packaging, pinout, peripheral mapping, and electrical specifications. The only functional difference is Flash memory size: 8KB+256B for MSP430F123IPWR-HYD versus 4KB+256B for MSP430F122IPWR. Firmware compiled for one will run on the other if code size permits, with no hardware or layout changes required.
