• On-chip RAM: 2 to 32 KB

Code flash memory

• Code flash memory: 16 to 512 KB

• Block size: 1 KB

• Prohibition of block erase and rewriting (security function)

• On-chip debug function

• Self-programming (with boot swap function/flash shield window function)

Data Flash Memory

• Data flash memory: 4 KB to 8 KB

• Back ground operation (BGO): Instructions can be executed from the program memory while rewriting the data flash memory.

• Number of rewrites: 1,000,000 times (TYP.)

• Voltage of rewrites: VDD = 1.8 to 5.5 V

High-speed on-chip oscillator

• Select from 32 MHz, 24 MHz, 16 MHz, 12 MHz, 8 MHz, 6 MHz, 4 MHz, 3 MHz, 2 MHz, and 1 MHz

• High accuracy: +/- 1.0 % (VDD = 1.8 to 5.5 V, TA = -20 to +85°C)

Operating ambient temperature

• TA = -40 to +85°C (A: Consumer applications, D: Industrial applications )

• TA = -40 to +105°C (G: Industrial applications)

Power management and reset function

• On-chip power-on-reset (POR) circuit

• On-chip voltage detector (LVD) (Select interrupt and reset from 14 levels) DMA (Direct Memory Access) controller

• 2/4 channels

• Number of clocks during transfer between 8/16-bit SFR and internal RAM: 2 clocks Multiplier and divider/multiply-accumulator

• 16 bits × 16 bits = 32 bits (Unsigned or signed)

• 32 bits ÷ 32 bits = 32 bits (Unsigned)

• 16 bits × 16 bits + 32 bits = 32 bits (Unsigned or signed)

Serial interface

• Simplified SPI (CSI Note 1): 2 to 8 channels

• UART/UART (LIN-bus supported): 2 to 4 channels

• I2C/Simplified I2C communication: 3 to 10 channels

Timer

• 16-bit timer: 8 to 16 channels

• 12-bit interval timer: 1 channel

• Real-time clock: 1 channel (calendar for 99 years, alarm function, and clock correction function)

• Watchdog timer: 1 channel (operable with the dedicated low-speed on-chip oscillator) A/D converter

• 8/10-bit resolution A/D converter (VDD = 1.6 to 5.5 V)

• Analog input: 6 to 26 channels

• Internal reference voltage (1.45 V) and temperature

sensor Note 2

I/O port

• I/O port: 16 to 120 (N-ch open drain I/O [withstand voltage of 6 V]: 0 to 4, N-ch open drain I/O [VDD withstand voltage Note 3/EVDD withstand

voltage Note 4]: 5 to 25)

• Can be set to N-ch open drain, TTL input buffer, and on-chip pull-up resistor

• Different potential interface: Can connect to a 1.8/2.5/3 V device

• On-chip key interrupt function

• On-chip clock output/buzzer output controller

Others

• On-chip BCD (binary-coded decimal) correction circuit Notes 1. Although the CSI function is generally calledSPI, it is also called CSI in this product, so itis referred to as such in this manual.

2. Can be selected only in HS (high-speed main)mode

3. Products with 20 to 52 pins

4. Products with 64 to 128 pins
