Product details
Overview
MA320018 from Microchip Technology is a PIC32MZ2048 EF Audio Plug-In Module (PIM) designed for Bluetooth and digital audio development on the PIC32 Bluetooth Audio Development Kit. It integrates a 200 MHz MIPS32 M-Class core with FPU, 2 MB Flash, 512 KB SRAM, I²S/SPI audio interfaces, 48-channel 12-bit ADC, Hi-Speed USB 2.0, and crypto engine - enabling real-time audio processing and secure wireless streaming.
For engineers reviewing the MA320018 datasheet, MA320018 pinout, MA320018 application, or MA320018 equivalent, this module is specifically optimized for Bluetooth audio subsystem integration, requiring precise I²S timing alignment, low-latency DMA routing to audio peripherals, and secure firmware signing via its hardware crypto engine.
Technical Context
The MA320018 implements the PIC32MZ2048EFG144 microcontroller in a 144-pin TQFP package, configured with full audio peripheral enablement including dual I²S controllers, PPS-mapped audio clock routing, and dedicated DMA channels for concurrent I²S transmit/receive operations. Its memory map allocates 2 MB dual-panel Flash for live firmware updates and 512 KB SRAM with cache-enabled data paths to sustain real-time audio buffering at 48 kHz/24-bit stereo.
Hardware crypto acceleration supports AES-128/256, SHA-256, and RSA key generation directly offloaded from the MIPS32 core - critical for Bluetooth Secure Simple Pairing (SSP) and Over-The-Air (OTA) firmware validation. The module's EBI and PMP are disabled in this configuration, prioritizing audio interface bandwidth and power efficiency over external memory expansion.

FAQ
What is the MA320018 and how does it differ from other PIC32MZ PIMs?
The MA320018 is a PIC32MZ2048 EF Audio Plug-In Module optimized for Bluetooth audio development on the PIC32 Bluetooth Audio Development Kit. Unlike the MA320019 (designed for Explorer 16 with Ethernet/CAN focus), the MA320018 enables I²S-based digital audio streaming, features full crypto engine activation for Bluetooth security, and disables EBI/PMP to prioritize audio peripheral bandwidth and power efficiency.
Which microcontroller is used on the MA320018 module?
The MA320018 integrates the PIC32MZ2048EFG144 microcontroller - a 144-pin TQFP device with 200 MHz operation, 2 MB Flash, 512 KB SRAM, dual I²S, hardware crypto engine, and AEC-Q100 Grade 1 qualification. This exact MCU variant is pre-configured and validated for audio-specific peripheral routing and timing in the MA320018 module.
Is the MA320018 compatible with the Explorer 16 Development Board?
No, the MA320018 is explicitly not compatible with the Explorer 16 Development Board. Its pinout, power sequencing, and I²S/audio signal routing are tailored for the PIC32 Bluetooth Audio Development Kit. Attempting to use MA320018 on Explorer 16 may result in incorrect audio clock distribution, missing crypto engine initialization, or mechanical interference due to differing mounting constraints.
Does the MA320018 support live firmware updates?
Yes, the MA320018 leverages the dual-panel Flash architecture of the PIC32MZ2048EFG144 to support atomic live firmware updates without interrupting audio playback. This capability is enabled by factory-programmed bootloader partitioning and verified in Microchip's MPLAB Harmony Audio Framework v3.8+ for seamless OTA upgrades in Bluetooth speaker and headset designs using MA320018.
What audio sample rates and formats does the MA320018 support natively?
The MA320018 supports I²S master/slave modes at standard consumer audio rates: 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz, with 16-/24-bit linear PCM data packing. Its dual I²S controllers allow simultaneous stereo playback and mono capture, and the 48-channel ADC supports analog microphone input with programmable gain amplifiers - all coordinated via hardware-triggered DMA to minimize CPU load during MA320018 audio processing.
