RF Keyboard Encoder
1 General Description
In RF keyboard system, that is divided into two parts (the transmitter and the receiver).
The eKK6511 micro-controller is dedicated to a RF keyboard encoder for single
channel RF transmitter module. The eKK6511 is scanning keyboard state, encode key
data and rely on RF Tx module to transmit data.
2 Features
Low cost – eliminate need external components.
Phantom key detect.
Resonator oscillator (2.00 MHz)
Low power CMOS device technology
Internal pull-up resistor.
Tri-state outputs for easy board application.
Built-in 4K ROM.
Support WINDOWSTM 95, 98, 2000 keys.
104/107 keys with multi-media or other special keyboard encoder.
Support RF transmit module sleep mode (Sleep current under 10µA).
Warm-up time of RF Tx modules: 7.2µ sec
Using the device ID to identify which receiver was connected.
DIP switch to select. (8 sets ID)
Random generate ID (255 sets ID) and store in EEPROM (93LC46)
Package: 40-pins PDIP, 44-pins QFP
