Core and memory profile
The MSP430F5326IZQER is a 16-bit microcontroller built around the MSP430 CPUXV2 core, running at 25 MHz. It packs 96 KB of program Flash and 8 KB of RAM — enough headroom for a moderate sensor-fusion or control loop without external memory.
47 general-purpose I/O lines give plenty of pins for parallel buses, keypad matrices, or discrete sensor inputs. On-chip peripherals include a 12-channel 12-bit ADC, brown-out detect, DMA, POR, PWM, and a watchdog timer — enough to handle closed-loop motor control or data acquisition without external analog front-end components. Connectivity covers I²C, SPI, UART/USART, IrDA, and LINbus, so the part can talk to serial sensors, displays, or a CAN transceiver through the LIN interface.
Housed in an 80-ball VFBGA (BGA Microstar Junior, 5×5 mm), the part demands a multi-layer PCB for fan-out — the 0.5 mm ball pitch rules out two-layer routing for all 47 I/O. The 80-BGA package footprint is compact enough for space-constrained designs like handheld instruments or sensor nodes. Supplied in tape & reel (also cut tape), it is pick-and-place ready for high-volume assembly. The MSL level is not stated in this record, so the moisture-sensitive floor life should be confirmed from the TI datasheet before opening the reel.
Lifecycle reality — obsolete, sourced to order
Texas Instruments has marked the MSP430F5326IZQER as Obsolete. No official successor or pin-compatible replacement is listed in this record. A BOM review for a drop-in alternative from the MSP430F5xx family (same package, similar memory) is advisable before committing a new build.
