ST22FJ1M - STMicroelectronics

ST22FJ1M Smartcard 32-Bit RISC MCU

The ST22FJ1M is a member of the SmartJ™ platform using a 32-bit Reduced Instruction Set Computer (RISC) core to execute both Native RISC instructions and JavaCard™ 2.x Technology instruction (byte codes) directly. Direct JavaCard™ byte code execution provides high performance advantage over processors that emulate the JavaCard™ byte code instruction set. – T.
