PCMCIA Miniature Card: Miniature Card is a smaller implementation of PCMCIA. Miniature Cards dimensions: 3.5mm x 33mm x 38mm (Tall x Length x Width). The electrical specifications are a subset of the PC Card standard, restricted to memory applications only. It uses a 16-bit data bus and a 24-bit address bus to allow a single card to store up to 64MB. Miniature Card is used as a memory-only expansion card or Linear Flash interface. Miniature Card Supports addressing up to 64M Bytes of Flash, DRAM [32M words], or ROM memory and uses a 16-bit Non-multiplexed Data Bus. Supplied power is either 5.0 or 3.3volts. The table below shows the pin-out for a 60 pin connector.
