Product Overview
The MSP430G2201 is a Texas Instruments ultralow-power mixed-signal MCU built around the MSP430 16-bit RISC CPU. It operates over a 1.8 V to 3.6 V supply range and supports five software-selectable low-power modes, with 220 µA active-mode current at 1 MHz and 2.2 V, 0.5 µA standby current, and 0.1 µA off-mode current with RAM retention.
For program and data storage, the device provides 2 KB Flash and 128 B RAM. The CPU includes 16 registers and a 51-instruction set with three instruction formats and seven address modes. Clock options include LF, DCO, and VLO sources, with an internal DCO frequency up to 16 MHz.
Peripheral and system features include 10 I/O pins, one 16-bit Timer_A with two capture/compare registers, WDT+, an on-chip brownout detector, and one EEM emulation module. Programming and test access are supported through Spy-Bi-Wire / JTAG, with no external programming voltage required and programmable code protection by security fuse.
