Product details

The Microchip ATMEGA88PB-ANR is an 8-bit AVR microcontroller from the ATmega series, part of the Functional Safety (FuSa) portfolio.

Housed in a 32-TQFP package with a 7x7 mm body, the ATMEGA88PB-ANR is a surface-mount device with a 0.8 mm pitch. The 27 I/O are accessible on all four sides, which simplifies routing on a two-layer board. The exposed pad (if present on this variant) should be stitched to the ground plane with a few vias for thermal relief — the datasheet's recommended footprint is the safe starting point.

The base product number ATMEGA88 means the PB suffix adds the picoPower and improved EMC features of the later revision — a direct drop-in for older ATMEGA88P designs if the firmware is recompiled for the same peripheral set.

Frequently asked questions

Is ATMEGA88PB-ANR RoHS compliant?

Yes, the ATMEGA88PB-ANR is ROHS3 compliant, meaning it meets the EU RoHS directive without lead, mercury, cadmium, or other restricted substances above the threshold limits.

Can I use ATMEGA88PB-ANR as a replacement for ATMEGA88P?

Yes, the ATMEGA88PB is a direct functional upgrade over the ATMEGA88P, adding picoPower technology and improved EMC performance. The pinout and memory map are compatible, but firmware should be recompiled to account for any peripheral timing differences. The base product number ATMEGA88 confirms the same core architecture.
