Product details

Overview

MSP430F2013CY from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 2KB+256B flash memory, 128B RAM, and a 16-bit Sigma-Delta ADC with differential PGA inputs and internal reference. It operates from 1.8 V to 3.6 V and supports five power-saving modes, enabling sub-1 µs wake-up from standby - ideal for battery-powered sensor front ends and portable measurement systems.

For engineers reviewing the MSP430F2013CY datasheet, MSP430F2013CY pinout, MSP430F2013CY application, or MSP430F2013CY equivalent, key selection considerations include its SD16_A 16-bit sigma-delta ADC resolution and input structure, USI support for SPI/I²C, Spy-Bi-Wire debug interface, TSSOP-14 package compatibility, and -40°C to 85°C industrial temperature grade.

Technical Context

The MSP430F2013CY implements a 16-bit RISC CPU with constant generators and seven addressing modes, executing instructions in 62.5 ns at 16 MHz. Its basic clock module integrates a digitally controlled oscillator (DCO) with factory-calibrated frequencies up to 16 MHz (±1%), plus support for 32-kHz crystal and internal low-frequency oscillators.

Peripheral integration includes Timer_A2 with two capture/compare registers, Universal Serial Interface (USI) configurable for SPI or I²C, brownout detection, and on-chip emulation logic. The SD16_A module provides 16-bit sigma-delta conversion with differential analog inputs (A0± through A3±), programmable gain, and internal voltage reference - all operating within the same ultra-low-power envelope as the core.

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice

FAQ

What is the maximum operating frequency of the MSP430F2013CY CPU?

The MSP430F2013CY CPU supports a maximum system clock (MCLK) of 16 MHz, enabled by its factory-calibrated digitally controlled oscillator (DCO). This frequency is achievable without external components and maintains ±1% accuracy across temperature and voltage - confirmed in the SLAS491I datasheet Section 5.2 (Basic Clock Module Configurations). The MSP430F2013CY achieves 62.5-ns instruction cycle time at this rate.

Does the MSP430F2013CY support hardware I²C communication?

Yes, the MSP430F2013CY supports hardware I²C via its Universal Serial Interface (USI) module. Pins P1.6 (SCL) and P1.7 (SDA) are dedicated USI functions, and the USI can be configured in I²C mode with automatic start/stop detection and address matching. This capability is documented in the SLAS491I datasheet Section 1.1 (Features) and Table 4 (Terminal Functions for MSP430F20x3).

What analog input configurations does the SD16_A module on the MSP430F2013CY support?

The SD16_A module on the MSP430F2013CY supports fully differential analog inputs with programmable gain (1×, 2×, 4×, 8×, 16×) across four independent channels: A0±, A1±, A2±, and A3±. It also accepts external reference voltage via P1.3 (VREF/A1−) and uses an internal 1.2-V reference. These configurations are specified in the SLAS491I datasheet Section 1.1 and Table 4 (Terminal Functions).

Is the MSP430F2013CY pin-compatible with other devices in the MSP430F20xx family?

Yes, the MSP430F2013CY shares identical pinout and package (14-pin TSSOP) with all MSP430F20xx variants including MSP430F2001, MSP430F2011, MSP430F2002, MSP430F2012, and MSP430F2003. Pin assignments for P1.x, XIN/XOUT, RST/NMI/SBWTDIO, TEST/SBWTCK, VCC, and VSS are functionally consistent across the family - verified in Tables 2–4 and device pinout diagrams in SLAS491I.

What debug interface does the MSP430F2013CY use, and what connections are required?

The MSP430F2013CY uses the Spy-Bi-Wire (SBW) interface, a 2-wire variant of JTAG. Only two connections are required: TEST/SBWTCK (pin 11) and RST/NMI/SBWTDIO (pin 10). No external programming voltage is needed - the interface operates from the device's VCC supply. This is confirmed in the SLAS491I datasheet Section 1.1 (Features) and Table 4 (Terminal Functions).
