The PIC32CX1012BZ25048T-E/MYX supports Bluetooth 5.2 (certified), Zigbee 3.0, Thread 1.3.0, and IEEE 802.15.4 with full hardware MAC acceleration for all protocols. Its shared transceiver and hardware radio arbiter enable concurrent operation - for example, maintaining a BLE connection while relaying Zigbee messages - without CPU intervention or external protocol co-processors.
Does the PIC32CX1012BZ25048T-E/MYX include hardware cryptographic accelerators?
Yes, the PIC32CX1012BZ25048T-E/MYX integrates multiple hardware security blocks: an AES engine supporting 128/192/256-bit keys at up to 2 MB/s, a True Random Number Generator (TRNG), a Public Key Cryptography Controller (PUKCC) with ECC-GF(p) and RSA support, and an Integrity Check Module (ICM) for SHA1/SHA224/SHA256. These accelerate secure boot, BLE pairing (ECDH-P256), and OTA updates in PIC32CX1012BZ25048T-E/MYX-based designs.
What is the operating temperature range and qualification status of the PIC32CX1012BZ25048T-E/MYX?
The PIC32CX1012BZ25048T-E/MYX is AEC-Q100 Grade 1 qualified for automotive use, with guaranteed operation from –40°C to +125°C ambient temperature. This qualification covers the full SoC - including RF transceiver, PMU, and memory subsystems - and is validated per stress test requirements for humidity, thermal cycling, and ESD immunity, making it suitable for under-hood and cabin applications.
How does the PIC32CX1012BZ25048T-E/MYX manage power in ultra-low-power applications?
The PIC32CX1012BZ25048T-E/MYX implements six power modes - Run, Idle, Dream, Sleep, Deep Sleep, and Extreme Deep Sleep - with sub-1 µA retention current in Extreme Deep Sleep. Its Sleep Walking peripherals (e.g., ADC, RTC, event system) operate autonomously without CPU wake-up, and the integrated PMU supports on-the-fly switching between buck (DC-DC) and MLDO modes to optimize efficiency across load conditions in PIC32CX1012BZ25048T-E/MYX deployments.
Is the PIC32CX1012BZ25048T-E/MYX pin-compatible with other members of the PIC32CX-BZ2 family?
No - the PIC32CX1012BZ25048T-E/MYX uses a 48-pin QFN package, while the PIC32CX1012BZ24032 uses a 32-pin QFN. Pin counts, layouts, and peripheral mappings differ between variants; migration requires PCB redesign. However, firmware is binary-compatible across the PIC32CX-BZ2 family due to identical memory map, register layout, and instruction set - easing software reuse when scaling between PIC32CX1012BZ25048T-E/MYX and smaller variants.
