Detailed Description

16-bit ultra-low-power microcontroller in a 100-LQFP package with 512KB Flash and 32KB SRAM. Runs up to 25MHz on the MSP430 CPUXV2 core. Built-in LCD driver, 4x 24-bit Sigma-Delta converters, 8-channel 10-bit ADC, rich communication interfaces (I2C, IrDA, LINbus, SPI, UART/USART). Operates from 1.8V to 3.6V, industrial temperature range -40°C to +85°C. Ideal for precision metering, portable instruments, and low-power embedded control.

Packaging

Type: LQFP, 100 leads

Supplier device package: 100-LQFP (14x14 mm)

Mounting: Surface mount

Delivery format: Tray

Material: Standard epoxy molding compound with copper leadframe and lead plating (industry standard for LQFP)

Size: Body ~14 x 14 mm; fine-pitch gullwing leads (refer to datasheet for exact pitch/lead dimensions)

Pin configuration: 100 pins with 62 GPIO available; pins support multiple functions (ADC, SD24, LCD, serial interfaces)

Thermal characteristics: Operates from -40°C to +85°C ambient; thermal performance depends on PCB copper area and airflow; no exposed thermal pad. For detailed θJA/θJC values and thermal guidelines, see the datasheet.

Electrical properties relevant to package: ESD protection integrated at I/O; supply 1.8V–3.6V; internal oscillator; consult datasheet for specific pin ratings, drive strengths, and capacitances.
