Features

Key Features

  • Arm® Cortex®-M33 96MHz with 396 CoreMark (4.12 CoreMark/MHz)
  • Up to 1MB Flash, up to 128KB SRAM, 8 kB SRAM with ECC
  • All RAM can be retained down to Deep Power-down mode
  • -40 °C to 125 °C temperature range

Core Platform

  • Arm 32-bit Cortex-M33 CPU, with FPU and DSP extension instruction set, no TrustZone, no MPU

Memory

  • Single-bank Flash: Up to 1024 kB Flash with ECC (supports one bit correction and two-bits detection)
  • Flash minimum programming size is 16 bytes
  • Support Flash Swap with 8 kB granularity
  • Cache Engine with 4 kB RAM
  • Up to 128 kB RAM, configurable for up to 8 kB with ECC (support single bit correction, two-bits detection)
  • All RAM can be retained down to deep Power-down mode

Peripherals

  • Analog
    • Up to two single-ended 16-bit ADC with sample rate of 4.0 Msamples/sec in 12-bit mode, and 3.2Msamples/sec in 16-bit mode. Up to 32 ADC input channels with multiple internal and external trigger inputs
    • One integrated temperature sensor per ADC
    • One 12-bit DAC
    • Two high-speed comparators with 8 input pins and an 8-bit DAC as internal reference, one comparator is functional down to deep Power-down mode, can be used as a wake-up source from low-power modes
    • One OpAmp supports PGA
  • Timers
    • Up to five 32-bit standard general-purpose asynchronous timers/counters, each timer supports up to four capture inputs and four compare outputs; specific timer events can be selected to generate DMA requests
    • Low power timer
    • Frequency measurement timer
    • Windowed watchdog Timer
    • Wake timer
    • Microtick timer (UTICK) that runs from the 1 MHz clock. This can wake up the device from reduced power modes up to deep sleep with Flash off, with extremely low power consumption
    • 42-bit free running OS timer as a continuous timebase for the system, available in any reduced power modes
  • Communication Interfaces
    • USB 2.0 full speed device controller with on-chip PHY supporting crystal-less operation in device mode
    • Up to two LPSPI modules, supporting up to 50MHz operation frequency in primary mode
    • Up to four LPI2C supporting Standard, Fast, Fast+ and Ultra Fast modes
    • Up to five LPUART provides asynchronous, serial communication capabilities
    • One I3C bus interface
    • One FlexIO programmable as a variety of serial and parallel interfaces, including, but not limited to display driver and camera interface (depending on part number)
    • One FlexCAN with FD (depending on part number)
  • Advanced Motor Control subsystem
    • Up to two FlexPWM each with 3 submodules, providing 12 complementary outputs of PWM (no Nanoedge module)
    • Up to two Quadrature Decoder (eQDC), provides interfacing capability to position/speed sensors used in industrial motor control applications
    • Up to two AOI (AND/OR/Invert) module support up to 4 output trigger

MCUXpresso Developer Experience

Security

  • Device Life-cycle management
  • Flash read/write/execute permission protect by MBC and lockable
  • 128-bit Universal unique identifier (UUID) per device in accordance to IETF’s RFC4122 version 5 specification
  • Code watchdog and glitch attack resistant keyed access (Glikey) support security monitoring

Packaging

  • HVQFN32 (5x5 mm), HVQFN48 (7x7 mm), LQFP48 (7x7 mm), LQFP64 (10x10 mm), LQFP100 (14x14 mm), LFBGA64 (5x5 mm), VFBGA112 (7x7 mm)
