ST22L064 - (ST22L032 - ST22L128) Smartcard 32-Bit RISC MCU

Download the ST22L064 datasheet PDF. This datasheet also covers the ST22L032 variant, as both devices belong to the same (st22l032 - st22l128) smartcard 32-bit risc mcu family and are provided as variant models within a single manufacturer datasheet.

General Description

The ST22Lxxx 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(See Figure 2.

"SmartJ™ Platform EEPROM Architecture", on page 3).
