2.
Internal peripheral resources
General-purpose ports : Maximum 73 ports
DMAC (DMA Controller)
Maximum of 5 channels able to operate simultaneously.
2 transfer sources (internal peripheral/software)
Activation source can be selected using software.
Addressing mode specifies full 32-bit addresses (increment/decrement/fixed)
Transfer mode (demand transfer/burst transfer/step transfer/block transfer)
Transfer data size selectable from 8/16/32-bit
Multi-byte transfer enabled (by software)
DMAC descriptor in I/O areas (200H to 240H, 1000H to 1024H)
A/D converter (successive approximation type)
10-bit resolution: 26 channels
Conversion time: minimum 1
μs
External interrupt inputs : 10 channels
Shares the CAN RX pin and the I2C SDA pin
Bit search module (for REALOS)
Function to search from the MSB (most significant bit) for the position of the first “0”, “1”, or changed bit in a word
LIN-USART (full duplex double buffer): 5 channels
Clock synchronous/asynchronous selectable
Sync-break detection
Internal dedicated baud rate generator
I2C bus interface (supports 400 kbps): 1 channel
Master/slave transmission and reception
Arbitration function, clock synchronisation function
CAN controller (C-CAN): 1 channel
Maximum transfer speed: 1 Mbps
32 transmission/reception message buffers
16-bit PPG timer : 12 channels
16-bit reload timer: 8 channels
16-bit free-run timer: 8 channels (1 channel each for ICU and OCU)
Input capture: 8 channels (operates in conjunction with the free-run timer)
Output compare: 8 channels (operates in conjunction with the free-run timer)
Watchdog timer
Real-time clock
Low-power consumption modes : Sleep/stop mode function
Supply Supervisor: Low voltage detection circuit for external VDD5 and internal 1.8V core voltage
Clock supervisor
Monitors the sub-clock (32 kHz) and the main clock (4 MHz) , and switches to a recovery clock (CR oscillator,
etc.) when the oscillations stop.
