A, Z and X version differences Feature A version Z version X version ARM7TDMI core device Identification (ID) code register (see ARM7TDMI Technical Reference Manual) Version bits [31:28] = 0001 Version bits [31:28] = 0010 Version bits [31:28] = 0010 Low power mode consumption in STOP mode at 25 °C Not guaranteed Typical 49 µA 50 µA maximum at 25°C. Less than 30 µA at 25 °C for 99.730020% of parts Same as Z. SC.DATA pin Not TRUE open drain When addressing 5V cards, the SCDATA Line must be connected to an open drain buffer. Pin P0.10/U1.RX/U1.TX/SC. DATA has been modified to offer TRUE OPEN DRAIN functionality when in SmartCard mode. When addressing 5V cards, the SCDATA line can now be connected directly to the card I/O. This modification is backward compatible with previous designs, and no board modification is required. |
