MCUs for advanced security and physical protection

29 May 2019 DSP, Micros & Memory

The new K32 microcontroller (MCU) series from NXP Semiconductors is optimised for energy efficiency in real-time embedded applications, and enables advanced security with physical tamper protection in a wide range of industrial and Internet of Things (IoT) applications. The power-efficient devices complement the recently launched performance-efficient LPC5500 MCU series.

Building upon the adoption of the Kinetis MCU platform, the K32 series targets energy efficiency for low duty-cycle applications with a wide operating voltage range, and ultra-low leakage power modes that support full SRAM retention and fast wake-up.

First to launch in the series is the K32 L3 family, a 72 MHz Arm Cortex M4-based MCU with an optional Cortex M0+. The device offers up to 1,25 MB Flash memory and 384 KB SRAM, with numerous serial communication interfaces, 12-bit 1 MSps analog-to-digital converter (ADC), 10-bit digital-to-analog converter (DAC) and comparator, 32-bit PWM timer modules, and an external memory controller for flexible expansion. The complete K32 L3 family is planned to support Flash sizes from 512 KB to 1,28 MB, but the full range is available for immediate development from the initial superset.

Other key features include: fast wake-up from 2 μA current with partial SRAM retention, and 7 μA current with full SRAM retention; and a single inductor, multiple output (SIMO) DC-DC converter to maximise energy efficiency, with the added flexibility to provide core power as well as two independent I/O rails, up to 1.8 V.

As little as 200 nA is consumed in always-on VBAT mode, with 32K low-power RTC oscillator and register retention and four tamper pins for physical tamper protection. The MCUs offer an uncompromised Root-of-Trust (RoT) with authenticated boot, encrypted firmware update and storage of public key hash in one-time programmable (OTP) memory. Hardware acceleration is provided for symmetric (AES-256, DES/3DES) and asymmetric (RSA 4096-bit public key, ECC) cryptography, along with SHA-256 hashing and true random number generator (TRNG) with 512 bits of entropy.
