The MSP430F233TPM: 48 I/O lines support parallel sensor arrays or display segments.
Housed in a 64-LQFP package (10x10 mm), the MSP430F233TPM is a surface-mount device.
On-chip peripherals include brown-out detection, power-on reset, PWM generation, and a watchdog timer — the basic supervisory and timing blocks needed for standalone control without external supervisor ICs.
The MSP430F233TPM is the TPM-suffix variant (tray packaging) of the MSP430F233 base part. The base product number MSP430F233 covers the same die in different shipping media. For a pin-compatible upgrade with more memory, look at the MSP430F241x or MSP430F261x series in the same 64-LQFP package — but verify the exact memory and peripheral map against your firmware size and ADC requirements.
The core runs at 16 MHz, which is the maximum clock frequency supported by the MSP430 CPU16 with zero-wait-state Flash access. This speed is adequate for control loops, sensor polling, and communication protocol handling at moderate data rates.
