16-Bit Security Controller with MMU in 0.25µm CMOS Technology

72-Kbytes ROM, 2304 bytes RAM, 16-Kbytes EEPROM

Features

• 16-bit microcomputer in 0.25 µm CMOS

technology

• Instruction set opcode compatible with

standard SAB 8051 processor

• Enhanced 16-bit arithmetic

• Additional powerful instructions optimized

for chip card applications

• Dedicated, non-standard architecture with

execution time 6 times faster (18 times

by PLLmax) than standard SAB 8051

processor at same external clock

• 70 Kbytes User ROM for application

programs

• Additional 2 Kbytes reserved ROM for

Resource Management System (RMS+

light) with intelligent EEPROM write/erase

routines

• 16 Kbytes Slim-EEPROM

• 2 Kbytes XRAM, 256 Bytes IRAM

• Memory Management and Protection

Unit (MMU)

• CRC Module

• Interrupt Module

• Two 16-bit Autoreload Timer

• PLL

• Power saving sleep mode

• External clock frequency 1 to 7.5 MHz

for internal clock

≤ 10 MHz

• UART for handling serial interface in

accordance with ISO/IEC 7816 part 3

supporting transmission protocols T=1

and T=0

• I/O routines realized in software executable

• Supply voltage range: 2.7 V to 5.5 V

• Current consumption

< 10 mA @ 5.5 V

< 6 mA @ 3.3 V

• Temperature range: -25 to +85°C

• ESD protection larger than 6 kV

Slim-EEPROM

• Reading, erasing and writing byte by byte

• Flexible page mode for 1 to 64 bytes

write/erase operation

• 32 bytes security area (OTP)

• Erase + Write time < 4.5 ms

• Minimum of 500.000 write/erase cycles at

25°C

• Data retention for a minimum of 10 years

• EEPROM programming voltage generated on

chip

Memory Management and Protection Unit

• Addressable memory up to 1 Mbyte

• Separates OS (system) and application

(user)

• System routines called by traps

• OS can restrict access to peripherals in

application mode

• Code execution from XRAM possible

Security Features

Operation state monitoring mechanism

• Low and high voltage sensors

• Frequency sensors and filters

Memory Security

• 16 bytes security PROM, hardware

protected

• Unique chip identification number for each

chip

• MED - memory encryption/decryption device

for XRAM, ROM and EEPROM

• True Random Number Generator with

Firmware test function

• Security optimised layout and layout

scrambling
