What this MSP430F5436AIZCAT brings to the BOM
It runs at 25MHz and carries 192KB of Flash program memory with 16K x 8 of RAM, enough for moderate firmware stacks and data logging without external memory. The 87 I/O lines give it the pin count for sensor arrays, keypads, or parallel LCD interfaces. On-chip peripherals include a brown-out detect and reset, DMA controller, POR, PWM timers, and a watchdog timer — the usual set for reliable standalone operation in motor control, industrial sensors, and building automation. Connectivity covers I²C, IrDA, LINbus, SCI, SPI, and UART/USART, so it talks to most serial peripherals without glue logic. The 12-bit ADC with 16 channels handles analog inputs from thermocouples, current shunts, or potentiometers directly.
Package and rework — 113-NFBGA
This part comes in a 113-VFBGA package, specifically the 113-NFBGA (7x7) variant. The 7x7 mm body saves board area but demands careful PCB layout. The supply voltage range of 1.8V to 3.6V covers single-cell Li-ion and 3.3V regulated rails.
Lifecycle and sourcing
For production planning and MRO stock, this means it remains a viable BOM line without imminent obsolescence risk. The base product number is MSP430F5436, so future die revisions or package variants should carry the same base for cross-reference tracking.
