LPC55S28JEV98K Description
The LPC55S28JEV98K is an ARM Cortex-M33-based microcontroller for embedded applications. These devices include a CASPER Crypto/FFT engine, up to 256 KB of on-chip SRAM, up to 512 KB on-chip flash, PRINCE module for on-the-fly flash encryption/decryption, high-speed and full-speed USB host and device interface with the crystal-less operation for full-speed, SD/MMC/SDIO interface, five general-purpose timers, one SCTimer/PWM, one RTC/alarm timer, one 24-bit Multi-Rate Timer (MRT), a Windowed Watchdog Timer (WWDT), nine flexible serial communication peripherals (which can be configured as a USART, SPI, high-speed SPI, I2C, or I2S interface), Programmable Logic Unit (PLU), one 16-bit 1.0 Msamples/sec ADC, comparator, and temperature sensor.
The LPC55S28JEV98K additionally supports secure boot, HASH, AES, RSA, UUID, dynamic encrypt and decrypt, debug authentication, and TBSA compliance to fulfill security requirements.
LPC55S28JEV98K Features
Uses RSASSA-PKCS1-v1_5 signature of SHA256 digest as cryptographic signature verification.
Supports RSA-2048 bit public keys (2048 bit modulus, 32-bit exponent).
Supports RSA-4096 bit public keys (4096 bit modulus, 32-bit exponent).
Uses x509 certificate format to validate image public keys.
Supports up to four revocable Root of Trust (RoT) or Certificate Authority keys, Root of Trust establishment by storing the SHA-256 hash digest of the hashes of four RoT public keys in protected flash region (PFR).
Supports anti-rollback feature using image key revocation and supports up to 16 Image key certificates revocations using Serial Number field in x509 certificate.
? Flexcomm Interface contains up to nine serial peripherals (Flexcomm Interface 0-7 and Flexcomm Interface 8). Each Flexcomm Interface (except flexcomm 8, which is dedicated for high-speed SPI) can be selected by software to be a USART, SPI, I2C, and I2S interface. Each Flexcomm Interface includes a FIFO that supports USART, SPI, and I2S. A variety of clocking options are available to each Flexcomm Interface, including a shared fractional baud-rate generator, and time-out feature.Flexcomm interfaces 0 to 7 each provide one channel pair of I2S.
I2C-bus interfaces support Fast-mode and Fast-mode Plus with data rates of up to 1Mbit/s and with multiple address recognition and monitor mode. Two sets of true I2C pads also support high-speed Mode (3.4 Mbit/s) as a slave.
USB 2.0 full speed host/device controller with on-chip PHY and dedicated DMA controller supporting crystal-less operation in device mode using software library example in technical note (TN00063).
