Overview
PIC32CX5109BZ31032-V/RTB from Microchip Technology is a 32-bit Bluetooth Low Energy 6.0 and IEEE 802.15.4 SoC with ARM Cortex-M4F core running at 64 MHz, integrated 2.4 GHz transceiver (–95 dBm RX sensitivity @ 2 Mbps BLE), 512 KB Flash, 96 KB SRAM, and AEC-Q100 Grade 2 qualification for automotive-grade IoT edge nodes.
For engineers reviewing the PIC32CX5109BZ31032-V/RTB datasheet, PIC32CX5109BZ31032-V/RTB pinout, PIC32CX5109BZ31032-V/RTB application, or PIC32CX5109BZ31032-V/RTB equivalent, key selection criteria include its 14 GPIO count, 32-pin QFN package, dual-protocol wireless stack support (BLE 6.0 + 802.15.4), hardware AES128/ECDH-P256 accelerators, and secure boot ROM with asymmetric verification.
Technical Context
This SoC integrates a shared 2.4 GHz RF transceiver supporting concurrent BLE 6.0 and IEEE 802.15.4 PHY/MAC layers, with programmable TX power (–24 to +11 dBm in 1 dB steps) and hardware-assisted MAC features including auto-ack, auto-retry, and address filtering. Its security subsystem includes dedicated eFuse storage (3072-bit), TRNG compliant with NIST SP 800-90B, and ROM-based secure boot enforcing signature validation before execution.
The device implements Sleep-Walking peripherals and five low-power modes (Run, Idle, Standby Sleep, Deep Sleep, Extreme Deep Sleep), enabling sub-μA retention current. Its analog subsystem combines a 12-bit 1 Msps SAR ADC (4-channel), 7-bit DAC, and capacitive touch support via CVD using shared ADC resources - all operating within 1.9–3.6 V across –40 °C to +105 °C.
