1. Overview

Temperature sensor

 1 channel

 Relative precision: ±1.0°C

 The voltage of the temperature is converted into a digital value by the 12-bit A/D

converter (unit 2).

Arithmetic unit for trigonometric functions

(TFUv2)

 Calculation of sine, cosine, arctangent, and hypotenuse

Simultaneous calculation of sine and cosine

Simultaneous calculation of arctangent and hypotenuse

Safety

Memory protection unit

(MPU)

 Protection area: Eight areas (max.) can be specified in the range from 0000 0000h to

FFFF FFFFh.

 Minimum protection unit: 16 bytes

 Reading from, writing to, and enabling the execution access can be specified for each

area.

 An access exception occurs when the detected access is not in the permitted area.

Trusted Memory (TM)

Function

 Programs in the TM target area in the code flash memory are protected against reading

 Instruction fetching by the CPU is the only form of access to these areas when the TM

function is enabled.

function

 Protects important registers from being overwritten for in case a program runs out of

control.

CRC calculator (CRCA)

 Generation of CRC codes for 8-/32-bit data

8-bit data

Selectable from the following three polynomials

X8 + X2 + X + 1, X16 + X15 + X2 + 1, X16 + X12 + X5 + 1

32-bit data

Selectable from the following two polynomials

X32+X26+X23+X22+X16+X12+X11+X10+X8+X7+X5+X4+X2+X+1,

X32+X28+X27+X26+X25+X23+X22+X20+X19+X18+X14+X13+X11+X10+X9+X8+X6+1

 Generation of CRC codes for use with LSB-first or MSB-first communications is

selectable

Main clock oscillation

stop detection function

 Main clock oscillation stop detection: Available

Clock frequency

accuracy measurement

circuit (CAC)

 Monitors the clock output from the main clock oscillator, low- and high-speed on-chip

oscillators, IWDT-dedicated on-chip oscillator, and PCLKB.

Data operation circuit

(DOCA)

 This handles the comparison, addition, subtraction, comparison in terms of which is

larger or smaller, or window comparison of 32-bit values.

Encryption

functions

Trusted Secure IP

(TSIP-Lite)

 Access management circuit

 Encryption engine

128- or 256-bit key sizes of AES

Block cipher mode of operation: GCM, ECB, CBC, CMAC, XTS, CTR, GCTR

 Hash function

 True random number generator

 Prevention from illicit copying of a key

Operating frequency

Up to 120 MHz

Power supply voltage

VCC = 2.7 to 5.5V

AVCC0 = AVCC1 = AVCC2 = 3.0 to 5.5V (VCC ≤ AVCC0 = AVCC1 = AVCC2)

VSS = AVSS0 = AVSS1 = AVSS2 = 0V

Operating temperature

D-version: –40 to +85°C

G-version: –40 to +105°C
