3 GENERAL DESCRIPTION

The PCA5007 pager baseband controller is manufactured

in an advanced CMOS/OTP technology.

The PCA5007 is an 8-bit microcontroller especially suited

for pagers. For this purpose, features such as a

4 or 2 level FSK demodulator, filter, clock recovery,

protocol timer, DC/DC converter optimized for small

paging systems and RTC are integrated on-chip.

The device is optimized for low power consumption.

The PCA5007 has several software selectable modes for

power reduction: Idle and power-down mode of the

microcontroller, and standby and off mode of the DC/DC

converter.

The instruction set of the PCA5007 is based on that of the

80C51. The PCA5007 also functions as an arithmetic

processor having facilities for both binary and BCD

arithmetic plus bit-handling capabilities. The instruction set

consists of over 100 instructions: 49 one-byte,

46 two-byte, and 16 three-byte.

This data sheet details the properties of the PCA5007.

For details of the I2C-bus functions see “The I2C-bus and

how to use it”. For details on the basic 80C51 properties

and features see “Data Handbook IC20”.
