Product details
Overview
MCXN236VNLT from NXP Semiconductors is an Arm Cortex-M33 150 MHz 32-bit microcontroller with TrustZone, 1 MB Flash, 352 KB SRAM, EdgeLock Secure Enclave (Core Profile), and operation from –40 °C to +125 °C. It delivers 618 CoreMark® (4.12 CoreMark/MHz), supports dual-bank Flash swap with ECC, and enables secure industrial motor control and edge AI inference in energy-constrained environments.
For engineers reviewing the MCXN236VNLT datasheet, MCXN236VNLT pinout, MCXN236VNLT application, or MCXN236VNLT equivalent, key selection criteria include its 100-pin HLQFP package, 2 Msps 16-bit dual ADC with 61-channel support, FlexCAN FD interfaces, low-power modes down to 1.5 μA, and hardware-accelerated cryptographic services including AES-256, SHA-2, and ECC P-256.
Technical Context
The MCXN236VNLT integrates a dual-core-capable Arm Cortex-M33 CPU with FPU, SIMD, ETM, and CTI, coupled with SmartDMA for parallel camera interface and keypad scanning acceleration. Its memory subsystem includes two 512 KB Flash banks supporting Read-While-Write and ECC, plus configurable SRAM up to 352 KB with optional ECC on 288 KB.
Security is implemented via EdgeLock Secure Enclave (Core Profile) with TRNG, DICE-based device attestation, Physically Unclonable Function (PUF)-derived UID, immutable ROM bootloader, and tamper detection across voltage, temperature, light, clock, and six dedicated tamper pins - all operating within the same die as the main MCU core.

Pinout & Package
MCXN236VNLT uses a 100-pin HLQFP package (14 × 14 × 1.4 mm, 0.5 mm pitch) with five independent IO power domains (VDD, VDD_P2, VDD_P3, VDD_P4, VDD_BAT), supporting flexible voltage scaling and isolation between analog, digital, and always-on subsystems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_CORE | Digital core supply | 1.045 V nominal (0.95–1.26 V range); powers Cortex-M33 core, cache, and AHB matrix - requires strict POR sequencing after VDD_SYS. |
| VDD_SYS | System regulator supply | 1.71–1.98 V; powers internal LDOs, clocks, and HVD/LVD supervisors - must ramp before VDD_CORE and after VDD. |

FAQ
What is the operating temperature range for the MCXN236VNLT?
The MCXN236VNLT operates across –40 °C to +125 °C, qualified per automotive and industrial standards. This wide range enables deployment in harsh environments such as motor drive inverters, outdoor energy meters, and factory-floor HMIs where ambient temperatures exceed 85 °C. The device maintains full SRAM retention and cryptographic operation throughout this range.
Does the MCXN236VNLT support CAN FD communication?
Yes, the MCXN236VNLT integrates two FlexCAN modules with full CAN FD support (up to 5 Mbps data phase), enabling high-bandwidth diagnostics and firmware updates in industrial networks. Both controllers support ISO 11898-1:2015 compliance, flexible bit timing, and hardware message filtering - essential for time-critical motion control and distributed I/O systems.
How does the EdgeLock Secure Enclave function in the MCXN236VNLT?
The EdgeLock Secure Enclave (Core Profile) in the MCXN236VNLT provides isolated cryptographic services including AES-256, SHA-2, ECC P-256, TRNG, and secure key storage with usage policies. It enables device attestation via DICE, protects manufacturing keys with PUF-derived UID, and enforces secure boot - all implemented in dedicated hardware separate from the main Cortex-M33 core.
What low-power modes are available on the MCXN236VNLT and their typical current draw?
The MCXN236VNLT offers Deep Power-down (1.5 μA, RTC + 32 KB SRAM), Power-down (2.39 μA, full 352 KB SRAM), and Deep Sleep (124 μA, full SRAM retention). These modes are validated at 3.3 V and 25 °C per datasheet Section 2.1. Wake-up latency from Deep Power-down is 5.6 ms, making it suitable for battery-powered predictive maintenance sensors.
Is the MCXN236VNLT pin-compatible with other MCXN23x variants in the HLQFP100 package?
Yes, all MCXN23x devices in the 100-pin HLQFP package - including MCXN236VKLT, MCXN235VKLT, and MCXN236VNLT - share identical pinouts and footprint. This allows direct substitution during prototyping or qualification, provided firmware accommodates differences in Flash/SRAM size and tamper pin count (2 vs. 6 in VFBGA variants).
