FAQ
What Wi-Fi standards does the PIC32MZ2051W104132-I/NX support?
The PIC32MZ2051W104132-I/NX supports IEEE 802.11b/g/n in the 2.4 GHz ISM band (2400–2483.5 MHz) with single-stream (1×1) 20 MHz bandwidth. It is interoperable with Wi-Fi 6 and Wi-Fi 7 infrastructure but does not implement 802.11ax or 802.11be physical layers. The PIC32MZ2051W104132-I/NX achieves up to 20.5 dBm TX power in 802.11b mode when paired with an external front-end module.
Does the PIC32MZ2051W104132-I/NX include hardware cryptographic acceleration?
Yes, the PIC32MZ2051W104132-I/NX integrates a dedicated crypto engine supporting AES-128/256 (ECB/CBC/CTR/GCM), SHA-1/256, HMAC, TRNG, and asymmetric operations including 256-bit ECC, ECDH, ECDSA, Curve25519, and Ed25519 - all with DMA offload. This eliminates software bottlenecks in TLS handshakes and secure boot verification, directly accelerating the PIC32MZ2051W104132-I/NX's role in zero-trust architectures.
What is the minimum operating current in Deep Sleep mode for PIC32MZ2051W104132-I/NX?
The PIC32MZ2051W104132-I/NX achieves 1.9 µA typical current consumption in Deep Sleep mode and 1.11 µA typical in Extreme Deep Sleep mode, both with 8 KB context SRAM retained. These values are measured under specified conditions (2.97–3.63 V, –40°C to +85°C) and enable multi-year battery life in intermittent-reporting applications such as asset trackers - a key specification confirmed in DS70005425P page 1.
How many GPIO pins does the PIC32MZ2051W104132-I/NX provide?
The PIC32MZ2051W104132-I/NX provides up to 62 GPIO pins (RPn/RAx–RKx), all supporting Peripheral Pin Select (PPS) for full remapping of UART, SPI, I²C, USB, CAN, and other peripherals. This flexibility allows routing critical interfaces away from noisy sections of the PCB - a verified capability documented in Section 13.4 "Peripheral Pin Select (PPS)" of the PIC32MZ W1 Family Reference Manual referenced in DS70005425P.
Is the PIC32MZ2051W104132-I/NX pin-compatible with other PIC32MZ W1 devices?
Yes, the PIC32MZ2051W104132-I/NX shares identical 132-pin DQFN packaging, pinout, and footprint with PIC32MZ1025W104132-I/NX per DS70005425P Table 3 and packaging diagrams (pages 5–7). Both devices use the same mechanical outline, EPAD grounding requirement, and signal naming convention - enabling direct substitution in existing layouts when upgrading Flash/SRAM capacity.
