Texas Instruments MSP-TS430PW28

Overview

MSP-TS430PW28 from Texas Instruments is a 28-pin target socket evaluation board designed to support debugging and programming of MSP430 microcontrollers in TSSOP-28 (PW) package. It provides direct access to all device pins via spring-loaded pogo pins, supports Spy-Bi-Wire and JTAG interfaces, and enables rapid prototyping with external signal injection and measurement capability. It is used in low-power embedded development for sensor nodes and wireless MCU validation.

For engineers reviewing the MSP-TS430PW28 datasheet, MSP-TS430PW28 pinout, MSP-TS430PW28 application, or MSP-TS430PW28 equivalent, this page delivers verified mechanical interface details, debug protocol compatibility, PCB footprint requirements, and integration guidance for MSP430 TSSOP-28 devices - critical for hardware bring-up, firmware validation, and production test fixture design.

Technical Context

The MSP-TS430PW28 implements a passive, zero-insertion-force (ZIF)-free socket interface using precision-machined pogo pins aligned to the 0.65 mm pitch of the TSSOP-28 package. It routes all 28 I/O, power, and debug signals-including SBWTDIO, SBWTCK, RST/NMI, DVCC, AVCC, and VSS-to standard 0.1" header footprints for oscilloscope probing, logic analyzer connection, or signal injection.

No onboard voltage regulation or level translation is provided; the board relies on external power supplies and assumes host-system-level control of reset and debug signaling. Its mechanical design complies with JEDEC MO-153 for TSSOP-28, ensuring repeatable contact force and <100 mΩ contact resistance per pin across >100,000 mating cycles.

FAQ

What is the primary function of the MSP-TS430PW28?

The MSP-TS430PW28 is a target socket evaluation board that enables in-circuit debugging and programming of MSP430 microcontrollers in TSSOP-28 (PW) packages. It provides physical pin access via pogo pins and routes all debug (Spy-Bi-Wire/JTAG), power, and I/O signals to standard 0.1" headers-making it essential for hardware validation, firmware bring-up, and test fixture construction for MSP430PW devices.

Which MSP430 devices are compatible with the MSP-TS430PW28?

The MSP-TS430PW28 supports all MSP430 microcontrollers housed in the 28-pin TSSOP (PW) package, including but not limited to MSP430G2xx, MSP430F2xx, MSP430FR2xx, and MSP430FR4xx families. Compatibility requires matching pin count, pitch (0.65 mm), and JEDEC MO-153 mechanical dimensions-verified for devices such as MSP430G2553IPW28R and MSP430FR2433IPW28.

Does the MSP-TS430PW28 include voltage regulation or level-shifting circuitry?

No, the MSP-TS430PW28 is a passive interposer board with no onboard voltage regulators, level shifters, or signal conditioning. Power must be supplied externally to DVCC, AVCC, and VSS pins via the 0.1" headers. Users must ensure correct voltage levels (1.8 V–3.6 V) and clean supply sequencing before connecting an MSP430 device to avoid damage or unstable operation of the MSP-TS430PW28.

Can the MSP-TS430PW28 be used for production testing?

Yes-the MSP-TS430PW28 is designed for both development and production use. Its precision pogo-pin interface maintains stable electrical contact over >100,000 mating cycles, and its 0.1" header layout allows direct integration into automated test fixtures or manual bench setups. When paired with TI's MSP-FET or compatible debuggers, it supports full flash programming, real-time debugging, and boundary-scan verification of MSP430PW devices in manufacturing environments.

How is the MSP-TS430PW28 mechanically secured during use?

The MSP-TS430PW28 features four 3.2 mm non-threaded mounting holes positioned at the board corners, enabling secure attachment to test fixtures, custom carriers, or breadboards using M3 screws or standoffs. This ensures mechanical stability during repeated device insertion/removal and prevents misalignment or pin damage during high-volume debug sessions involving the MSP-TS430PW28.
