It delivers 64 MHz operation, 1 MB ECC Flash, 128 KB SRAM, -40°C to +125°C AEC-Q100 Grade 1 qualification, and hardware security accelerators (AES128/256, TRNG, PUKCC) for secure IoT edge nodes in automotive and industrial gateways.
For engineers reviewing the PIC32CX1012BZ25048T-I/MYX datasheet, PIC32CX1012BZ25048T-I/MYX pinout, PIC32CX1012BZ25048T-I/MYX application, or PIC32CX1012BZ25048T-I/MYX equivalent, this device enables rapid development of certified multi-protocol wireless endpoints requiring deterministic real-time control, low-power sleep walking peripherals, and on-chip cryptographic offload without external security ICs.
Technical Context
The PIC32CX1012BZ25048T-I/MYX integrates a shared 2.4 GHz transceiver with dual PA architecture (LPA +5 dBm / MPA +12 dBm), hardware radio arbiter for time-division coexistence between Bluetooth and IEEE 802.15.4, and dedicated 128-byte TX/RX frame buffers per protocol stack. Its PMU supports buck (DC-DC) and MLDO modes with on-the-fly selection across Run, Deep Sleep, and Extreme Deep Sleep states.
It features a 16-channel DMAC with CRC acceleration, four SERCOMs configurable as USART/I²C/SPI/LIN/RS485, two 24-bit TCCs with complementary PWM outputs and dead-time control, and a 12-bit SAR ADC with 2 Msps sampling rate and die temperature sensing - all accessible via flexible Peripheral Pin Select (PPS) routing.

FAQ
What wireless protocols does the PIC32CX1012BZ25048T-I/MYX support natively in hardware?
The PIC32CX1012BZ25048T-I/MYX supports Bluetooth 5.2 (certified), Zigbee 3.0, Thread 1.3.0, and IEEE 802.15.4 in hardware with dedicated MAC accelerators, independent TX/RX buffers, and a shared 2.4 GHz transceiver. Proprietary 500 Kbps–2 Mbps modes are also supported. All protocol stacks execute on the integrated ARM Cortex-M4 core with hardware offloads for scheduling, encryption, and packet arbitration - no external co-processor is needed for full protocol operation.
Does the PIC32CX1012BZ25048T-I/MYX include hardware security features required for secure boot and OTA updates?
Yes, the PIC32CX1012BZ25048T-I/MYX includes a complete hardware security suite: AES-128/192/256 engine (2 MB/s), TRNG, Public Key Cryptography Controller (PUKCC) with ECC GF(p) support, SHA-256 Integrity Check Module (ICM), and hardware white-list for BLE pairing. These enable secure boot with signature verification against OTP-stored public keys, authenticated OTA firmware updates, and end-to-end encrypted payload transmission - all without external secure elements.
What is the operating temperature range and automotive qualification status of the PIC32CX1012BZ25048T-I/MYX?
The PIC32CX1012BZ25048T-I/MYX is rated for -40°C to +125°C ambient operation and is AEC-Q100 Grade 1 qualified. This certification confirms its suitability for under-hood and cabin automotive applications, including vibration, thermal cycling, and ESD robustness testing per automotive standards - making it appropriate for production automotive IoT nodes without derating or additional qualification effort.
How does the PIC32CX1012BZ25048T-I/MYX manage power in ultra-low-power applications like battery-operated sensors?
The PIC32CX1012BZ25048T-I/MYX implements six power modes - Run, Idle, Dream, Sleep, Deep Sleep, and Extreme Deep Sleep - with sub-µA retention current. Its Sleep Walking peripherals autonomously sample ADC, trigger timers, and respond to events while the CPU remains powered down. The integrated PMU supports on-the-fly switching between buck (high-efficiency) and MLDO (low-noise) regulators, and the RF transceiver achieves -97 dBm BLE sensitivity at 1 Mbps - extending battery life in intermittent-sensing applications beyond 5 years on a CR2032 cell.
Is the PIC32CX1012BZ25048T-I/MYX pin-compatible with other members of the PIC32CX-BZ2 family, such as the PIC32CX1012BZ24032T-I/MV?
No, the PIC32CX1012BZ25048T-I/MYX is not pin-compatible with the PIC32CX1012BZ24032T-I/MV. The former uses a 48-pin QFN (7 mm × 7 mm), while the latter uses a 32-pin QFN (5 mm × 5 mm). Pin counts, spacing, thermal pad layout, and peripheral signal assignments differ. Migration requires PCB redesign; however, software compatibility is maintained across the PIC32CX-BZ2 family via unified HAL and MPLAB Harmony v3 framework support.
