Quantity : 5000   Price : $1.07

TDA8023 New and original in stock! Action Dynamic.
The TDA8023 is a complete cost-efficient, low-power analog interface for synchronous or asynchronous smart cards. It can be placed between the card and the microcontroller with very few external components to perform all supply, protection and control functions.

Features

  • I²C-bus controlled IC card interface in TSSOP28
  • Supply voltage from 2.7 V to 6.5 V
  • Independant supply voltage VDD(INTF) for interface signals with the microcontroller
  • Shutdown input for very low power consumption when the part is not used
  • Power reduction modes when the card is active
  • DC-to-DC converter for VCC generation (capacitive doubler, tripler, or inductive, or follower automatically selected according to supply voltage and card voltage)
  • 1 specific protected half duplex bidirectional buffered I/O line, with current limitation at +-15 mA, maximum frequency 1 MHz
  • 2 auxiliary card I/O lines controlled by I²C-bus (C4 and C8)
  • VCC regulation: 5 V, 3 V or 1.8 V +- 8 pct, ICC< 55 mA, current spikes of 40 nAs up to 20 MHz, with controlled rise and fall times, filtered overload detection approximately 80 mA,
