PCE84C882

The PCE84C882 is the enhanced version of the PCE84C886 having all the features of this device but in addition provides:
· Two dedicated power pins for the PLL oscillator circuit
· A choice of two mask-programmable prescaler values for the PLL oscillator
· A higher frequency OSD clock - up to 20 MHz
· An improved edge-sensitive counter (T3). Differences between the PCE84C882 and the PCE84C886 are shown in Table 1 and also highlighted throughout the document.

The PCE84C882 is a member of the 84CXXX CMOS microcontroller family. PCE84C882 is suitable for use with auto-sync monitors handling mode detection, digital and DPMS control and has an enhanced OSD facility for menu driving applications. The device uses the PCE84CXX processor core and has 8 kbytes of ROM and 192 bytes of RAM. I/O requirements are catered for with 12 general purpose bidirectional I/O lines plus 14 derivative I/O lines. 8 PWM analog outputs are available for analog control purposes and one 4-bit ADC. The device has an 8-bit counter, for use in pulse counting applications; an 8-bit timer/counter with programmable clock and an on-chip programmable PLL oscillator that generates the OSD clock. A master-slave I2C-bus interface and 2 directly testable lines are also available. The block diagram of the PCE84C882 is shown in Fig.1.
