Raspberry Pi RP2354A Microcontroller

The Raspberry Pi RP2354A is a variant of the RP2350-family of microcontrollers from Raspberry Pi. This RP2354A variant comes in a QFN-60 (7x7mm) package along with 2MB internal flash, 30 GPIO and 4 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/RP2354A 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/RP2354A 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

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
