Identical core size: 32-Bit Single-Core
Identical operating frequency: 32MHz
Identical program memory: 32KB FLASH
Identical RAM: 8K x 8
Identical EEPROM: 2K x 8
Identical voltage supply range: 1.62V ~ 3.63V
Identical I/O count: 25 pins
Identical connectivity: I2C, LINbus, SPI, UART/USART
Identical peripherals: Brown-out Detect/Reset, DMA, POR, PWM, WDT
Identical data converters: A/D 10x12b, D/A 1x10b

Matching Mechanical Specifications:

Identical package: 32-VQFN (5x5) Exposed Pad
Identical mounting type: Surface Mount
Identical operating temperature range: -40°C ~ 85°C

Matching Compliance & Certifications:
