S3C89V5

The S3C89V5 single-chip CMOS microcontroller is specially designed and packaged for "smart card" applications. The SAM88RC CPU architecture supports Stop and Idle power-down modes for reduced power consumption. To increase the general-purpose register space, the physical internal register file is logically expanded.

The S3C89V5 has 47K-byte of program memory (ROM), 16K-byte of data memory (EEPROM), 272-byte generalpurpose register file and 1024-byte data buffer (SRAM). The following peripherals are integrated on-chip:

  - Contact or Contactless mode detection automatically
  - ISO 7816 compatible asynchronous serial interface for contact operation
  - Energy extraction and supply regulation circuits, clock extraction from 13.56 MHz carrier
  - ISO 14443-2 compatible (Type B)
  - One 16-bit Random number generator
  - Hardware-level EEPROM write inhibit features for data security
  - Frequency/Voltage/Temperature/Light exposure/Decapsulation various detectors with flag/reset action
  - ROM,RAM,EEPROM BUS Scramble
  - Contact UART(T=0, and T=1)
  - Contactless UART(Type B)
  - 16bit timer
  - Hardware CRC logic for Type B
  - Hardware DES logic

Data of S3C89V5 can be loaded into the EEPROM in units ranging from one byte to 32-byte. A typical EEPROM erase or write operation takes 1.5 milliseconds.

S3C89V5, A simple yet effective hardware-level security feature based on abnormal voltage, frequency, decapsulation temperature and light exposure detection circuits keeps data stored in PROM/EEPROM.

The S3C89V5's 8-pin COB package and its serial I/O interface are fully compliant with ISO standards 7816, respectively.
