The RX671 group microcontrollers deliver superior real-time performance with the RXv3 core running at 120MHz. The HMI functions enable contactless operation by proximity switches and voice recognition, making it possible to realize hygienic HMI suitable for the new normal. A wide variety of packages, including the 4.5mm x 4.5mm 64-pin TFBGA, is all equipped with 2MB flash memory and 384KB SRAM to meet a wide range of needs with a single chip.

Features

  • 120MHz RXv3 core (707 CoreMark, 48.8 CoreMark/mA), double-precision FPU, and register bank save function that speeds up interrupt response
  • 2MB flash memory (60MHz read access, dual bank function), 384KB SRAM
  • 48-pin to 176-pin package lineup including ultra-small 64-pin TFBGA (4.5mm x 4.5mm)
  • Capacitive touch sensing unit and serial sound interface
  • SD host interface, USB 2.0 full speed, CAN 2ch, and QSPI supporting XIP mode
  • Encryption engine (AES, RSA, ECC, SHA, etc.), key management, access management circuit, flash memory protection
  • 2.7V to 3.6V single supply operation
  • Operating temperature: -40°C to 85°C or -40°C to 105°C
