256 KB Flash and 18 KB RAM — the memory budget for this MSP430
The MSP430F5335IPZR provides 74 I/O pins and a 16-channel 12-bit ADC for multi-sensor acquisition boards.
Peripherals and connectivity for system integration
An internal oscillator is included, so the device can run without an external crystal for cost-sensitive builds, though the internal accuracy will limit precision timing applications.
For volume production planning, the active status removes the urgency to qualify an alternate, though maintaining a second-source strategy across the MSP430F5xx family is always prudent for supply resilience.
Package and footprint — 100-LQFP
Supplied in a 100-pin LQFP package with a 14 mm x 14 mm body, this is a standard fine-pitch quad flat pack. The surface-mount footprint is common across many MSP430F5xx devices, so a board layout for the MSP430F5335IPZR can often accommodate a pin-compatible sibling with different memory or peripheral options without a PCB respin.
