Package: CP-40-71 (40-pin)

Notes

• Multiple power and ground pins are distributed throughout the package for low impedance and noise reduction.
• RESET is active low; pull high for normal operation.
• SPI interface operates in slave mode with active-low chip select.
• XTAL1/XTAL2 are for external crystal oscillator connection (32.768 kHz typical).
• IRQ0 and IRQ1 are programmable interrupt outputs.
• PM0/PM1 pins select power mode configuration.

Thermal performance is directly linked to printed circuit board (PCB) design and operating environment. Careful attention to PCB thermal design is required.

θJA and θJC are specified for the worst case conditions, that is, a device soldered in a circuit board for surface-mount packages.
