Texas Instruments MSP430G2513IPW20R

Overview

MSP430G2513IPW20R from Texas Instruments is an ultra-low-power 16-bit RISC mixed-signal microcontroller in 20-pin TSSOP package, featuring 16 KB flash, 512 B RAM, two 16-bit Timer_A modules with three capture/compare registers each, USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), on-chip comparator, and Spy-Bi-Wire debug interface - deployed in battery-powered sensor nodes and portable instrumentation.

For engineers reviewing the MSP430G2513IPW20R datasheet, MSP430G2513IPW20R pinout, MSP430G2513IPW20R application, or MSP430G2513IPW20R equivalent, key selection criteria include verified 16 KB flash memory size, confirmed 20-pin TSSOP (PW20) package mapping, validated 16-bit Timer_A dual-module configuration, functional USCI_A0/USCI_B0 peripheral availability, and exact ADC10 exclusion per device family specification.

Technical Context

The MSP430G2513IPW20R implements a 16-bit RISC CPU with constant generators and seven addressing modes, executing register-to-register operations in one CPU clock cycle. Its basic clock module integrates DCO (digitally controlled oscillator), internal LF oscillator, and external crystal support (32 kHz), enabling sub-1 µs wake-up from LPM4.

It supports five low-power modes (LPM0–LPM4), with active-mode current of 230 µA at 1 MHz/2.2 V and standby-mode current of 0.5 µA. The device lacks ADC10 - confirmed by Table 1 and repeated notes across datasheet sections - distinguishing it from MSP430G2x53 variants and aligning it with the G2x13 series feature set.

FAQ

What is the maximum operating frequency of the MSP430G2513IPW20R?

The MSP430G2513IPW20R features an internal digitally controlled oscillator (DCO) calibrated up to 16 MHz, with typical operation at 1 MHz in active mode. Its instruction cycle time is 62.5 ns at 16 MHz, but system design must account for voltage-dependent DCO stability - the device achieves full 16 MHz operation only above 2.2 V per SLAS735J specifications. MSP430G2513IPW20R supports multiple clock sources including external 32.768 kHz crystal for RTC accuracy.

Does the MSP430G2513IPW20R include an analog-to-digital converter (ADC)?

No, the MSP430G2513IPW20R does not include an ADC10 module. This is explicitly confirmed in Table 1 of SLAS735J, device pinout notes, and functional block diagrams - all identifying ADC10 as exclusive to MSP430G2x53 devices. The MSP430G2513IPW20R retains the full Comparator_A+ module with 8 channels and reference inputs (VREF+/VREF-) for analog threshold detection, making it suitable for comparator-based sensing without digitization.

What debug interface does the MSP430G2513IPW20R support?

The MSP430G2513IPW20R supports Spy-Bi-Wire (SBW), a 2-wire variant of JTAG implemented on pins RST/NMI/SBWTDIO (Pin 16) and TEST/SBWTCK (Pin 17). This interface enables full in-circuit debugging, flash programming, and real-time register inspection using TI's MSP-FET or compatible tools. Unlike full 4-wire JTAG, Spy-Bi-Wire conserves two pins while maintaining complete visibility into CPU state and memory - a key advantage for space-constrained 20-pin designs like MSP430G2513IPW20R.

What are the power supply requirements for the MSP430G2513IPW20R?

The MSP430G2513IPW20R operates from a single 1.8 V to 3.6 V supply on DVCC (Pin 1) referenced to DVSS (Pin 20). It does not require separate analog supply rails - AVCC and AVSS are not present in the 20-pin TSSOP package. All analog functions (Comparator_A+, reference inputs, USCI I²C pull-ups) share the DVCC rail, and internal voltage references derive from DVCC. Decoupling with a 100 nF ceramic capacitor between DVCC and DVSS is mandatory per TI layout guidelines for MSP430G2513IPW20R stability.

Is the MSP430G2513IPW20R pin-compatible with other MSP430G2xx devices in TSSOP-20 package?

Yes, the MSP430G2513IPW20R shares identical pinout and electrical characteristics with other MSP430G2xx devices in 20-pin TSSOP (PW20) package, including MSP430G2413IPW20, MSP430G2313IPW20, and MSP430G2213IPW20. All use the same top-view pin numbering, I/O functionality mapping (e.g., P1.x, P2.x, USCI, timers), and power/ground locations. This enables direct substitution within the G2x13 family for firmware-compatible upgrades or cost-optimized downgrades without PCB revision.
