3 / 108 page  1996 Jun 27 3 Philips Semiconductors Product specification 8-bit microcontroller with on-chip CAN P8xCE598 1 FEATURES • 80C51 central processing unit (CPU) • 32 kbytes on-chip ROM, externally expandible to 64 kbytes • 2 × 256 bytes on-chip RAM, externally expandible to 64 kbytes • Two standard 16-bit timers/counters • One additional 16-bit timer/counter coupled to four capture and three compare registers • 10-bit ADC with 8 multiplexed analog inputs • Two 8-bit resolution Pulse Width Modulated outputs • 15 interrupt sources with 2 priority levels (2 to 6 external interrupt sources possible) • Five 8-bit I/O ports, plus one 8-bit input port shared with analog inputs • CAN-controller (CAN = Controller Area Network) with DMA data transfer facility to internal RAM • 1 Mbit/s CAN-controller with bus failure management facility • 1⁄2AVDD reference voltage • Full-duplex UART compatible with the standard 80C51 • On-chip Watchdog Timer (WDT) • 1.2 to 16 MHz clock frequency • Improved Electromagnetic Compatibility (EMC). 2 GENERAL DESCRIPTION The P8xCE598 is a single-chip 8-bit high-performance microcontroller with on-chip CAN-controller, derived from the 80C51 microcontroller family. It uses the powerful 80C51 instruction set. Figure 1 shows a block diagram of the P8xCE598. The P8xCE598 is manufactured in an advanced CMOS process, and is designed for use in automotive and general industrial applications. In addition to the 80C51 standard features, the device provides a number of dedicated hardware functions for these applications. Two versions of the P8xCE598 will be offered: • P80CE598 (without ROM) • P83CE598 (with ROM) Hereafter these versions will be referred to as P8xCE598. The temperature range includes (max. fCLK = 16 MHz): •−40 to +85 °C version, for general applications •−40 to +125 °C version for automotive applications. The P8xCE598 combines the functions of P8XC552 (microcontroller) and the PCA82C200 (Philips CAN-controller) with the following enhanced features: • 32 kbytes Program Memory • 2 × 256 bytes Data Memory • DMA between CAN Transmit/Receive Buffer and internal RAM. The main differences to the P8xC552 microcontroller are: • 32 kbytes programmable ROM (P8xC552 has 8 kbytes) • Additional 256 bytes RAM • A CAN-controller instead of the I2C-serial interface. 2.1 Electromagnetic Compatibility (EMC) Primary attention is paid to the reduction of electromagnetic emission of the microcontroller P8xCE598. The following features reduce the electromagnetic emission and additionally improve the electromagnetic susceptibility: • One analog part power supply pin (AVDD) and one analog part ground pin (AVSS), placed as a pair of pins on one side of the package (see Fig.3), providing power supply (+5V) and ground for ADC, CAN receiver and reference voltage. • Four digital part supply voltage pins (VDD1 to VDD4) and four digital part ground pins (VSS1 to VSS4) are provided on the package. These pins, one VDD and one VSS as a pair of pins are placed on each of the four sides of the package to provide: –VDD1/VSS1 for internal logic (CPU, Timers/counters, Memory, CAN, UART, ADC) –VDD2/VSS2 for Port 1, Port 3 and Port 4, and PWM0 and PWM1 outputs –VDD3/VSS3 for the on-chip oscillator –VDD4/VSS4 for the Port 0, Port 2, ALE output and PSEN output. • External capacitors should be connected across associated VDDx and VSSx pins (i.e. VDD1 and VSS1). Lead length should be as short as possible. Ceramic chip capacitors are recommended (100 nF). • One CAN supply voltage pin (CVDD) and one CAN ground pin (CVSS) as a pair of pins placed on one side of the package providing (digital part) power supply (+5V) and ground for the CAN transmitter outputs. • Internal decoupling capacitance improves the EMC radiation behaviour and the EMC immunity. |
