NXP Unveils i.MX RT600 Series Arm Cortex-M33 + Audio DSP Crossover Processor

A little over a year ago, NXP introduces their first crossover processor that blurs the line between real-time capabilities of microcontrollers and higher performance of application processors with NXP i.MX RT1050 processor equipped with a Cortex-M7 core clocked at up to 700 MHz.

The company has now announced another model with lower power consumption. NXP i.MX RT600 series comes with a Cortex M33 core clocked at up to 300MHz, a Cadence Tensillica HiFi 4 audio DSP, and up to 4.5MB shared SRAM.

Main features of NXP i.MX RT685 crossover processor:

• CPU Core – Arm  Cortex-M33 up to 300 MHz
• DSP – Tensilica Hi-Fi 4 up to 600 MHz
• Memory
  • Up to 4.5 MB on-chip RAM
  • 128KB DSP TCM, 128 KB DSP Cache
• Storage
  • 96KB ROM on-chip
  • 2x SDIO with 1x supporting eMMC5.0 w/ HS400
  • 1x Octal/Quad SPI up to 100MB/s
• Peripherals
  • 2x DMA Engines with 35 channels each
  • 1x USB high speed host/device with PHY
  • 1x SPI  up to 50 MHz
  • Serial Interfaces – 8x FlexComm interfaces with support for up to 8x SPI, 8x I2C, 8x UART, 4x I2S channels (total 8 instances)
  • 1x I3C Master/Slave interface
  • Up to 8-channel DMIC (Digital MIC)
  • Up to 228 GPIO’s
  • 1x 12-bit ADC up to 1 Msps
  • 1x ACMP analog caparator
  • 1x Capacitive touch sensor
  • 1x Temperature sensor
  • Timers – 32-bit SCTimer, 24-bit multi-rate timer, 64-bit OS event timer, 5x GP timers, 2x watchdogs
• Security – SRAM PUF, RNG, AES256, SHA-2, Secure Boot, RNG
  ACMP
• Reduced-Power Modes – Sleep mode, deep-sleep mode and deep power-down mode
• Package – VFBGA176
• Operating Temperature – 0 to 70°C
• Manufacturing Process – 28nm FD-SOI technology

NXP I.MX RT600 family targets audio / IoT applications such as audio subsystems, ML-based edge applications, voice recognition consumer electronics, and voice UI-enabled IoT devices.

NXP i.MX RT600 is still at the pre-production stage, and AFAIK the company did not provide any launch date. Eventually more details should surface in the product page.
