GENERAL DESCRIPTION
· CMOS 8-bit CPU (enhanced 8048 CPU) with 4 kbytes system ROM and 128 bytes system RAM · One 8-bit timer/event counter (T1) and one 8-bit counter (T3) triggered by external input · Three single level vectored interrupt sources: external (INTN), counter/timer and I2C-bus · 2 directly testable inputs T0 and T1 · On-chip oscillator clock frequency: 1 to 10 MHz · On-chip Power-on-reset with low power detector · The PCE84C486 has eleven quasi-bidirectional I/O lines, the PCE84C487 has twelve. The configuration of each I/O line individually selected by mask option · Idle and Stop modes for reduced power consumption · Operating temperature: -25 to +85 °C · Operating voltage: 4.5 to 5.5 V · Packages: SDIP32 for the PCE84C486; SDIP42 for the PCE84C487. 1.2 Special I2C-bus interface
The PCE84C486 and PCE84C487 are low-cost microcontrollers and have been designed for use with auto-sync monitors, handling mode detection, digital control and Voltage Synthesized Tuning (VST). These microcontrollers have no on-chip OSD function. The term PCE84C48X is used throughout this data sheet to refer to both devices. Differences between the PCE84C486 and the PCE84C487 are highlighted throughout the document. The PCE84C48X is a member of the 84CXXX CMOS microcontroller family. The device uses the PCE84CXX processor core and has 4 kbytes of ROM and 128 bytes of RAM. I/O requirements are catered for with 11 general purpose bidirectional I/O lines (the PCE84C487 has 12) plus 12 function combined I/O lines (the PCE84C487 has 16). Nine PWM analog outputs (the PCE84C487 has 13) are available for analog control purposes and also a two channel 4-bit ADC. The device has an 8-bit counter (T3), for use in pulse counting applications and also an 8-bit timer/counter (T1) with programmable clock. A Watchdog timer, a master-slave I2C-bus interface and 2 directly testable lines are also available on-chip. The block diagram of the PCE84C486 is shown in Fig.1; the block diagram of the PCE84C487 is shown in Fig.2.
· Master-slave
· Four 6-bit Pulse Width Modulated outputs · Four 7-bit Pulse Width Modulated outputs · Four 8-bit Pulse Width Modulated outputs (PCE84C487 only) · One 14-bit Pulse Width Modulated output · Two 4-bit Analog-to-Digital Converter (ADC) channels · 14 derivative I/O ports · Watchdog Timer. 3 ORDERING INFORMATION PACKAGE TYPE NUMBER NAME PCE84C486 PCE84C487 SDIP32 SDIP42 DESCRIPTION plastic shrink dual in-line package; 32 leads (400 mil) plastic shrink dual in-line package; 42 leads (600 mil) VERSION SOT232-1 SOT270-1
