■ On-chip 32-bit Arm Cortex-R52 processor

● High-speed realtime control with operating frequency of 200/400

MHz

● On-chip Single 32-bit Arm Cortex-R52 (revision r1p2)

● Tightly coupled memory (TCM) with ECC

– CPU0: 128 KB/128 KB

● Instruction cache/data cache with ECC

– CPU0: 16 KB per cache

● High-speed interrupt

● The FPU supports addition, subtraction, multiplication, division,

multiply-and-accumulate, and square-root operations at singleprecision

and double-precision.

● The NEON, Advanced SIMD, supports integer or single precision

results.

● Harvard architecture with 8-stage pipeline

● Supports the memory protection unit (MPU)

● Arm CoreSight architecture, includes support for debugging

through JTAG and SWD interfaces.

■ Low power consumption

● Standby mode and module stop function

■ On-chip SRAM

● 1.5 MB of the on-chip SRAM with ECC

● 150/200 MHz

■ Data transfer

● DMAC: 8 channels × 2 units

■ Event link controller

● Module operations can be started by event signals rather than by

interrupt handlers.

● Linked operation of modules is available even while the CPU is in

the standby state.

■ Reset and power supply voltage control

● Four reset sources including a pin reset

■ Clock functions

● External clock/oscillator input frequency: 25 MHz

● CPU clock frequency: 200/400 MHz or 150/300 MHz

● System clock frequency: 200 MHz or 150 MHz

● Low-speed on-chip oscillator (LOCO): 240 kHz

■ Safety functions

● Register write protection, input clock oscillation stop detection and

CRC

● Master Memory Protection Unit (MPU)

■ Security functions (optional)

● Boot mode with security through encryption

● JTAG authentication

● Cryptologic accelerator

● TRNG

■ Various communications interfaces

● Ethernet

– EtherCAT slave Controller: 3 ports

– Ethernet switch: 3 ports

– Ethernet MAC: 1 port

● USB 2.0 high-speed host/functions: 1 channel

● CAN/CANFD (compliant with ISO11898-1): 2 channels

● SCI with 16-byte transmission and reception FIFOs: 6 channels

● I2C bus interface: 3 channel for transfer at up to 400 kbps

● SPI: 4 channels

● xSPI: 2 channels

■ External host interfaces
