The DS8007A multiprotocol dual smart card interface is an automotive grade, low-cost, dual smart card reader interface supporting all ISO 7816, EMV™, and GSM11-11 requirements.
The DS8007A is a multiprotocol dual smart‑card interface designed for automotive and low‑cost applications. It provides two independent smart‑card ports, an 8‑bit parallel bus, optional multiplexed operation, and an integrated UART for high‑speed communication.
The device includes built‑in voltage conversion for 1.8 V/3 V/5 V cards, supports T=0, T=1 and synchronous protocols, and offers extensive electrical specifications such as programmable FIFO depth and detailed timing parameters for both multiplexed and non‑multiplexed bus modes.

| Digital Supply Voltage (VDD) | 2.7 V – 6.0 V |
|---|---|
| Maximum Power Dissipation (TA = -25 °C) | 900 mW |
| Card Supply Voltage (5 V) – Current | 5.0 V ±5%, 65 mA (max) |
| Card Supply Voltage (3 V) – Current | 3.0 V ±8%, 50 mA (max) |
VDD can be supplied from 2.7 V up to 6.0 V.
The maximum power dissipation is 900 mW at –25 °C.
The DS8007A supports ISO 7816, EMV™ and GSM 11‑11, handling T=0, T=1 and synchronous protocols.
Yes, an evaluation kit (DS8007‑KIT) is available for development and testing.
