Raspberry Pi RP2354B Microcontroller

The Raspberry Pi RP2354B is a variant of the RP2350-family of microcontrollers from Raspberry Pi. This RP2354B variant comes in a QFN-80 (10x10mm) package along with 2MB internal flash, 48 GPIO and 8 analogue inputs We are stocking the latest A4 stepping, which has addressed a number of errata on the previous A2 version. Read more about the update here. The unique dual-core, dual-architecture capability of RP2350/RP2354B provides a pair of industry-standard Arm Cortex-M33 cores with hardware single-precision floating point and DSP instructions @150MHz, and a pair of open-hardware Hazard3 RISC-V cores, selectable in software or by programming the on-chip OTP memory. The RP2350/RP2354B has a comprehensive security architecture, built around Arm TrustZone for Cortex-M, along with a second-generation PIO subsystem that provides flexible interfacing with no CPU overhead. Sold in a pack of five. RP2350 Device Family Comparison

Product Package Internal flash GPIO Analogue inputs

RP2350A QFN-60 None 30 4

RP2350B QFN-80 None 48 8

RP2354A QFN-60 2 MB 30 4

RP2354B QFN-80 2 MB 48 8

RP2354A and RP2354B feature 2MB of internal flash. In all other respects, including pinout, they are identical to their flashless counterparts RP2350A and RP2350B. They use the same QFN-60 (RP2354A) and QFN-80 (RP2354B) packages. Important RP235x Design Guidelines

* Please read and follow the RP235x design guide

* Please refer to the datasheet, including errata and our reference design in KiCAD format

* Please use the 12 MHz Abracon ABM8-272-T3 crystal oscillator

* If using the on-chip SMPS, please use the custom polarised inductor from Abracon (AOTA-B201610S3R3-101-T) and orient it according to the instructions in the design guide
