Product Overview
The MSP430F5527 is a Texas Instruments ultra-low-power mixed-signal MCU built around the MSP430F552x 16-bit RISC architecture. It operates across a 1.8 V to 3.6 V supply range and supports a maximum system clock of 25 MHz. The MSP430F5527 device variant includes 96 KB flash and 8 KB + 2 KB RAM, with 63 I/O pins available in the listed family grouping.
For connectivity, the device integrates USB 2.0 full-speed with an integrated PHY, 8 input endpoints, 8 output endpoints, an integrated USB-PLL, and integrated 3.3 V and 1.8 V USB power system. Serial communication resources include enhanced UART with automatic baud-rate detection, synchronous SPI, and I2C support through the listed USCI functions.
Analog and timing resources include a 12-bit ADC12_A with 12 channels, internal reference, sample-and-hold, and autoscan support. Timer resources include Timer_A0 with 5 capture/compare registers, Timer_A1 and Timer_A2 with 3 capture/compare registers each, and Timer_B0 with 7 capture/compare shadow registers.
The MSP430F5527IPN package indication maps to an 80-pin LQFP package of approximately 12 mm x 12 mm. Low-power modes include LPM3 standby, LPM4 off mode, and LPM4.5 shutdown operation, supporting embedded control applications that require USB, sensing, serial communication, timing, and retained-memory low-power operation.
