Smart-card reader interface Smart-card reader ICs TDA8024 and TDA8034 These are complete, cost-efficient analog interfaces for asynchronous smart cards. They provide all the supply, protection, and control functions between a smart card and the microcontroller. The TDA8034 is the same as the TDA8024, but without a DC/DC converter. They are available with demo kits. The TDA8024 and TDA8034 are both NDS and EMV 4.2 compliant, and they both can supply a VCC of 5 V to the smart card. The system supply voltage influences device selection. Use the TDA8034 when the system supply voltage is 5 V +/- 3%. This will ensure that the card VCC value is a minimum of 4.75 V with a current load of 65 mA. In systems that can only supply a voltage of 5 V +/- 10%, the TDA8024 is a better choice, because it can guarantee a proper value on VCC = 5 V. The TDA8034 is available in a 24-pin HVQFN or, to meet low-cost requirements, can be housed in a 16-pin SO package. The TDA8034 is not pin-compatible with the TDA8024, which has 28 pins. L DO instead of DC/DC means that VDDP should be >4.85 V to guarantee VCC = 4.75 V min with 65 mA load On board oscillator or possibility to use external clock source on XTAL1 Shutdown mode on both packages Deep shutdown on HVQFN24 (<10 µA) TDA8034 block diagram Smart-card reader interface TDA8034 TDA8024 without DC/DC Smaller package HVQFN24 & SO16 NDS compliant (depending on package option) EMV compliant BCAS compliant 1.8, 3, and 5 V cards supported (on 24-pin version) 3 full-duplex I/O lines Synchronous clock division supported 8/4/2/1 Interface voltage VDDI down to 1.6 V 25 6.

Interfaces and control 8.1 8/16/32-bit microcontrollers 8.2 I2C GPIO expanders We offer highly-integrated and cost-effective microcontrollers, from the smallest 8-bit to the highest performing 32-bit ARM solutions. Our GPIO expanders make it easy to increase the number of I/O using the I2C-bus. Add inputs for a keypad, a switch, signal monitoring, or fan control, or add outputs for LED control, an ACPI power switch, a relay, timers, or sensors. The LPC111x family, based on Cortex-M0, is an excellent choice for standby microcontroller tasks. It can be used for power management, system and human interface monitoring (including remote control and keypad), signaling, LEDs, and more. The family delivers the outstanding performance of a 32-bit architecture, with best-in-class power consumption, and the optimized code footprint enables memory cost reduction. The NXP approach lets designers work with a single ARM development environment to cover all their processing needs, from ARM7 and ARM9 to Cortex-M.

D iscrete components for the main processing board 9.1 Power solutions Since integrated circuits typically use a lower core supply voltage than interfaces and memory devices, most boards require a number of different supply voltages. Our power solutions include a variety of devices, including medium-power Schottky diodes, bipolar transistors, and MOSFETs, to help create efficient, cost-effective linear regulators and DC/DC converters. The PBSS4041PZ can be used as a linear PNP regulator to generate 2.5 and 1.5 V analog supplies. It delivers excellent gain up to 15 A ICM while supporting 5.7 A of continuous current. Supporting 1.2 or 1.8 V, the PMEG2005EH, PMEG4010EH, and PMEG4030ER are excellent options for the freewheeling Schottky diodes commonly used in DC/DC conversion. The BSP030, a 10 A, N-channel MOSFET in an SOT233 package, can be used as an external MOSFET for synchronous rectification. The TL431xxSDT series of shunt regulators, along with the BC847, a general-purpose transistor, are recommended for low-power, discrete linear voltage regulators.

Components for the backlight and panel 10.1 LED drivers for panel backlight unit UBA3070 pin configuration (SO8 and DIP8) Our LED backlight solutions use a power-efficient boundary conduction mode of operation. This enables use of a smaller inductor value and avoids reverse recovery losses in the freewheel diode. It also enables use of a single, loosely controlled input voltage for multiple LED strings. UBA3070 LED driver for TV backlight Features Switch-mode buck converter capable of driving LED strings up to 600 V Direct PWM dimming Fast transient response through cycle-by-cycle current control - Prevents LED current over- and undershoots Zero-current switching at switch-on Zero-voltage or valley switching at switch-on Over-current and over-temperature protection, under-voltage lockout and leading edge blanking Available in DIP8 and SO8 packages 45 10. Components for the backlight and panel 10.2 Discretes for backlight and panel Our discretes portfolio covers other functions, too, including power for LCD source drivers, LCD backplane and digital controls, charge pumps, and load switches from 1 to 3 A. For example, the Schottky diodes can be used for buck, boost, and negative/positive charge pumps. The low VCEsat transistors support high-current load switches and Vcom buffers, and the medium-power transistors can be used for external, low-power linear regulators. Our discretes portfolio increases efficiency in LED backlight units. The high-voltage, low-voltage, and low VCEsat transistors enable cost-efficient emitter switches for high-voltage LED drivers and single switches in low-voltage LED strings. The small-signal MOSFETs are well suited for use in general-purpose single switches in low-voltage LED strings. The medium-power Schottky diodes can operate as freewheeling diodes that offer the lowest forward voltage drops, high power density, and superior efficiency.

RF communication with remote control unit To meet the growing demand to replace IR remote control with low-power, robust RF communication, NXP offers solutions based on the RF4CE standard protocol. JN5148 block diagram The JN5148 is especially well suited for high-end and connected TV applications, where it can be used as the core of a remote controller. It has the processing power to include “TV mouse” motion-sensing algorithms as well as running the RF4CE protocol. It can also be used as the power-management and wake-up controller of the TV set itself. In universal remotes, its dual-boot capability can be used to control consumer appliances running the RF4CE protocol as well as home-automation systems running ZigBee-HA or -SE protocols.
