Product details

The 87 I/O lines, wired through I²C, SPI, UART, LINbus, and IrDA interfaces, make it a fit for industrial control panels, field-instrument data loggers, and battery-powered telemetry nodes.

128 KB Flash / 16 KB RAM — firmware footprint and data buffer

128 KB of Flash is sized for a control firmware image with a modest RTOS kernel, communication stacks (Modbus RTU, CANopen via LIN-capable UART), and application logic. The 16 KB RAM is the tighter constraint: a large lookup table or a multi-frame data buffer for an external sensor will eat into that quickly. Designs that log many channels or store precomputed calibration curves should budget RAM usage early.

The MSP430F5419AIZCAT carries an end-of-life hot status. The manufacturer has issued a last-time-buy notice; new production allocations are closed or closing. For ongoing BOM lines, the procurement path is surplus and broker-channel sourcing.
