ST8024 - Brand New STMicroelectronics IC Chips
-
Description
The ST8024 is a complete low-cost analog interface for asynchronous 3V and 5V smart cards. It can be placed between the card and the microcontroller with few external components to perform all supply protection and control functions. The ST8024 is a direct replacement of the ST8004.
Specifications and features
- Designed to be compatible with the NDS conditional access system
- Thermal and short-circuit protection on all card contacts
- IC card interface
- 3 or 5V supply for the IC (VDDand GND)
- Three specifically protected half-duplex bidirectional buffered I/O lines to card contacts C4, C7, and C8
- DC-DC converter for VCC generation separately powered from a 5V ± 20% supply (VDDP and PGND)
- 3 or 5V ± 5% regulated card supply voltage (VCC) with appropriate decoupling has the following capabilities:
-- ICC < 80mA at VDDP = 4 to 6.5V
-- Handles current spikes of 40nA up to 20MHz
-- Controls rise and fall times
-- Filtered overload detection at approximately 120mA
- Automatic activation and deactivation sequences initiated by software or by hardware in the event of a short-circuit, card take-off, overheating, VDD, or VDDP drop-out
- Enhanced ESD protection on the card side (>6kV)
- 26MHz integrated crystal oscillator
- Clock generation for cards up to 20MHz (divided by 1, 2, 4, or 8 through CLKDIV1 and CLKDIV2 signals) with synchronous frequency changes
- Non-inverted control of RST via pin RSTIN
- ISO 7816, GSM11.11, and EMV (payment systems) compatibility
- Supply supervisor for spike-killing during power-on and power-off and power-on reset (threshold fixed internally or externally by a resistor bridge)
- Built-in debounce on card presence contacts
- One multiplexed status signal offApplication Scenarios
Due to its compatibility with the NDS conditional access system and its various protection and control functions, the ST8024 is suitable for a wide range of applications, including but not limited to:
- IC card readers
- Smart card-based systems
- Electronic payment devices
- Security systems
- Access control systemsComparison
