Product Overview
The MSP430G2452 is a Texas Instruments ultra-low-power mixed-signal MCU built around the MSP430 16-bit RISC CPU. It supports a 1.8-3.6 V operating supply range, a maximum 16 MHz internal DCO clock, four calibrated DCO frequencies, and a 62.5 ns instruction cycle time at the maximum CPU operating rate.
On-chip resources include 8 KB flash memory, 256 B RAM, one Timer_A3 with three capture/compare registers, an integrated brownout detector, and one EEM emulation module. The ADC10 subsystem provides 10-bit conversion at 200 ksps with 8 channels, an internal reference, sample-and-hold, and autoscan capability. The device also includes 8 comparator channels.
The MCU is available in 20-PDIP, 20-TSSOP, 16-QFN, and 14-TSSOP package cases. I/O availability is 16 pins for 20-pin package options and 10 pins for 14-pin TSSOP and 16-QFN options. Clocking supports LF, DCO, VLO, a 32 kHz crystal, and an external digital clock source. Serial connectivity is provided through one USI peripheral supporting SPI and I2C.
