Product details
Overview
MSP430A048IPM from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 64-pin QFP (PM) package, featuring 48 I/O pins, integrated 96-segment LCD driver, on-chip comparator, and FLL+ clock system. It operates from 1.8 V to 3.6 V and supports five power-saving modes with wake-up from standby in under 6 μs - ideal for battery-powered handheld meters and sensor interfaces.
For engineers reviewing the MSP430A048IPM datasheet, MSP430A048IPM pinout, MSP430A048IPM application, or MSP430A048IPM equivalent, key selection criteria include its 48 general-purpose I/O pins with LCD segment mapping, Timer_A3 with three capture/compare registers, brownout detection, and JTAG-based programming without external voltage.
Technical Context
The MSP430A048IPM implements a 16-bit RISC CPU with 125-ns instruction cycle time, constant generators, and seven addressing modes. Its FLL+ module locks DCO frequency to a programmable multiple of ACLK (e.g., 32.768 kHz crystal), enabling stable MCLK up to 8 MHz while maintaining sub-μA standby current.
It integrates Timer_A3 (three capture/compare registers), comparator_A with internal reference, SVS with programmable threshold (on select variants), and dedicated LCD control logic driving up to 96 segments via 4-mux configuration - all managed through memory-mapped peripherals accessible via standard instructions.

FAQ
What is the maximum operating frequency of the MSP430A048IPM?
The MSP430A048IPM supports a maximum MCLK frequency of 8 MHz, achieved via the FLL+ module locking the internal DCO to a crystal-derived reference (e.g., 32.768 kHz). This frequency is confirmed in the SLAS340J datasheet Section 10 (Operating Modes) and functional block diagrams, and defines the upper limit for CPU instruction execution and peripheral timing.
Does the MSP430A048IPM include flash memory, and what is its size?
Yes, the MSP430A048IPM contains 4 KB of on-chip flash memory for program storage, as specified in the "Family Members" table and memory organization diagram (Page 13) of SLAS340J. This matches the MSP430F412 device variant and supports in-system programming via JTAG or BSL.
How many LCD segments can the MSP430A048IPM drive, and what bias configurations are supported?
The MSP430A048IPM drives up to 96 LCD segments using its integrated controller with 1/2- or 1/4-bias capability, as stated in the device overview and functional block diagram (Page 4). COM0–COM3 outputs and segment pins (e.g., S0–S23, S10–S19) enable standard multiplexed LCD interfacing without external bias generation.
Is the MSP430A048IPM pin-compatible with other MSP430x41x family members in the 64-pin QFP package?
Yes, the MSP430A048IPM shares identical pinout and package (64-pin QFP, PM) with MSP430C412IPM, MSP430C413IPM, MSP430F412IPM, MSP430F413IPM, MSP430F415IPM, and MSP430F417IPM, as confirmed in the "AVAILABLE OPTIONS" table (Page 2) and pin designation diagrams (Pages 3–4) of SLAS340J.
What programming interfaces does the MSP430A048IPM support?
The MSP430A048IPM supports JTAG (TCK/TMS/TDI/TDO pins) and UART-based Bootstrap Loader (BSL) via P1.0 (TX) and P1.1 (RX). Both methods require no external programming voltage, and BSL access is protected by a user-configurable password per SLAA089 application report.
