Winbond Electronics Corporation W925C65
The W925E/C625 is an all-in-1 single 8-bit micro-controller with widely used Calling Identity Delivery (CID) function. The 8-bit CPU core is based on the 8051 family; therefore, all the instructions are compatible to the Turbo 8051 series. The CID part consists FSK decoder, DTMF receiver, CPE* Alert Signal (CAS) detector and Ring detector.| Part No. | W925C65 |

GENERAL DESCRIPTION
Also built-in DTMF generator and FSK generator with baud rate 1200 bps (bits/sec). Using W925E/C625 can easily implement the CID adjunct box and the feature phone or Short Message Service (SMS) phone with CID function. The main features are listed in the next section. 2FEATURES
● APPLICATION: The SMS phone with CID function and CID adjunct box.● CPU: 8-bit micro-controller is similar to the 8051 family. - Operating voltage: µC: 2.2 to 5.5 volt. CID: 3.0 to 5.5 volt.
● Dual-clock operation: - Main oscillator: 3.58MHz crystal for CID and DTMF function. And built-in RC oscillator. - Sub oscillator: 32768Hz crystal. - Main and sub oscillators are enable/disable by bit control individually.
● ROM: 64K bytes internal flash EEPROM/MASK ROM type. - up 64K bytes for program ROM. - total 64K bytes for look-up table ROM.
● RAM: - 256 bytes on chip scratch-pad RAM. - 4K bytes on chip RAM for MOVX instruction. - 224 bytes on chip LCD RAM.
● LCD: dot matrix control method. - 1792 dots: 56 Segments x 32 Common, 1/5 bias.
