The HTRC110 is a HITAG Reader Chip which is used for transponders, based on NXP semiconductors and is optimized for HITAG transponder ICs.
The HTRC110 is designed for almost complete integration of necessary building blocks. Integration into RF-identification readers prove to be easy as it supports 125KHz transponder types using amplitude modulation for the write operation and AM/PM for the read operation. The HTRC110 is programmed through a microcontroller that has 3 pins which is used for communication with transponders, it can be changed to a two wire interface if necessary by connecting the data input and data output.

The PCF8531 is a single-chip LCD controller and driver having 34 rows and 128 column outputs. It is intended to drive a dot matrix graphic display and has software selectable multiplex rates of 1:17, 1:26 and 1:34. Using a two-line bidirectional I2C bus for communication, the PCF8531 is compatible with most microcontrollers and all inputs are CMOS compatible.
An Icon mode is available with a multiplex rate of 1:2 that features a reduced current consumption when only icons are displayed. All necessary functions for the display are provided in a single chip, including on-chip generation of VLCD and the LCD bias voltages which result in a minimal need for external components and a much lower power consumption.
