8-bit MCU Series (80C51-based)

The W925EP01 is an all in one 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.That contains a 64K bytes of main Flash EPROM (APROM) and a 4K bytes of auxiliary Flash EPROM (LDROM) which allows the contents of the 64KB main Flash EPROM (APROM) to be updated by the loader program located at the 4KB auxiliary Flash EPROM (LDROM). W925EP01 CAN be extend to two 64KB program banks, there are APROM (00000H~0FFFFH) and external program ROM (10000H~1FFFFH), user CAN access the external ROM by P5, P6, P7, A16 and . All instructions are fetched for execution from this memory areas, the MOVC instruction CAN also access the external memory regions. The CID part consisted of FSK decoder, DTMF receiver, CPE* Alert Signal (CAS) detector and Ring detector. Also are built-in DTMF generator, FSK generator with baud rate 1200 bps (bits/sec) and CAS generator. Using W925EP01 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.
