General Description
The RTS8503H is a micro-controller with an 8-bit micro-processor (6502) embedded and it provides a complete
solution for the service of caller identification. The features and functions offered by the RTS8503H include FSK
demodulation, DTMF generation, Ring detection, LCD driver, Power Management and Low battery indication. The
FSK demodulator is designed for the Bell 202 and CCITT V.23 1200-baud asynchronous data and its performance
is compliant to the Bellcore GR-30-CORE. With 32K Bytes ROM embedded, it can help the designers easily and
flexibly to achieve the desired features. For these applications, it provides a one-chip solution for the adjunct boxes,
feature phones, and other communication systems.
