Features

Memory and Scalability

256 KB of Flash
256 KB of SRAM
CPU cache consisting of separate 8 KB I/D and 8 KB system cache
QSPI controller optimized for XIP from external serial NOR flash memories with support for quad and octal data interfaces
SDRAM and external memory bus interfaces
eMMC/SDIO interface through eSDHC peripheral

Ultra Low Power

Flexible low-power modes with power and clock gating for optimal peripheral activity and recovery times. Stop currents of <340 nA, run currents of 200 µA/MHz, 5.8 µs wake-up from Stop mode
Full memory and analog operation down to 1.71 volts for extended battery life
Low-leakage wake-up unit with up to seven internal modules and 24 pins as wake-up sources in low-leakage stop (LLS)/very low-leakage stop (VLLS) modes
Low-power peripherals and DMA for continuous system operation in reduced power state

Performance

Arm ® Cortex ®-M4 core + DSP up to 150 MHz, single-cycle MAC, single instruction multiple data (SIMD) extensions, single precision floating point unit
Up to 32-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
CPU cache consisting of separate 8 KB I/D and 8 KB system cache
Crossbar switch enables concurrent multi-leader bus accesses, increasing bus bandwidth

Cost Saving Integration

48 MHz internal reference clock capable of supporting full-speed USB device without an external crystal
Integrated USB regulator to allow direct connection to 5 V from USB cables
Separate I/O power domain for several pins allowing interfaces without external level translators
Analog voltage reference provides an accurate reference to analog blocks, ADC and DAC, and replaces external voltage references to reduce system cost

HMI (Human Machine Interface)

32-Pin FlexIO block capable of interfacing to camera or displays
External memory bus for connection to smart display modules
Touch Sense interface supported by Kinetis® SDK software library
GPIO pins with support for digital filtering

Mixed Signal Capability

16-bit analog-to-digital converter (ADC) with configurable resolution. Single or differential output mode operation for improved noise rejection
12-bit digital-to-analog converters (DACs) for analog waveform generation for audio applications
Two high-speed comparators providing fast and accurate motor over-current protection by driving PWMs to a safe state
Analog voltage reference provides an accurate reference to analog blocks, ADC and DAC, and replaces external voltage references to reduce system cost

Connectivity and Communications

USB 2.0 On-The-Go (full-speed) with USB transceiver. Intelligent design with embedded 48 MHz oscillator allowing for USB crystal-less system design. Device charge detect optimizes charging current/time for portable USB devices enabling longer battery life. Low-voltage regulator supplies up to 120 mA off-chip at 3.3 volts to power external components from 5 volts input
Up to four UARTs with IrDA support
EMVSIM module with ISO7816 smart card support
Inter-IC Sound (I2S) serial interface for audio system interfacing
Three DSPI and four I²C

Reliability and Safety

Memory protection unit provides memory protection for all leaders on the crossbar switch, increasing software reliability
Cyclic redundancy check engine validates memory contents and communication data, increasing system reliability
Independent-clocked COP guards against clock skew or code runaway for fail-safe applications such as the IEC 60730 safety standard for household appliances
External watchdog monitor drives output pin to safe state external components if watchdog event occurs

Advanced Security

Flash and chip security settings
Memory protection unit provides memory protection for all leaders on the crossbar switch, increasing software reliability
Hardware implementation of security operations Symmetrical crypto. Supports DES, 3DES, AES, MD5, SHA-1 and SHA-256 algorithms
Ability to disable JTAG and chip unique ID
ROM support for encrypted firmware updates
Flash Access controller to create execute only regions of embedded flash
Hardware crypto co-processor with support for DES, AES and Public key cryptography
On-the-fly AES decryption and execution from external serial NOR flash
Tamper detect module with detection temperature, voltage, clock or pin tampers with the ability to create active tamper meshes
2 KB of secure session RAM linked to the tamper detect module
