Product details

Overview

P80C592FFA/00,512 from Philips Semiconductors is an 8-bit microcontroller with integrated CAN 2.0A controller, 16 kB on-chip ROM, 512 bytes internal RAM (2 × 256), 10-bit ADC with 8 analog inputs, dual 8-bit PWM outputs, and five 8-bit I/O ports - designed for automotive and industrial real-time control systems requiring embedded CAN communication.

For engineers reviewing the P80C592FFA/00,512 datasheet, P80C592FFA/00,512 pinout, P80C592FFA/00,512 application, or P80C592FFA/00,512 equivalent, key selection criteria include CAN 1 Mbit/s compliance, 16 MHz max clock frequency, PLCC68 package compatibility, and integration of DMA-assisted CAN buffer transfers to internal RAM.

Technical Context

The P80C592FFA/00,512 implements an enhanced 80C51 CPU core with dedicated hardware blocks: a full CAN 2.0A controller supporting bus failure management, a 16-bit Timer T2 with four capture and three compare registers, and dual PWM channels sharing a common 8-bit prescaler and counter. Its memory architecture separates MAIN RAM (0–127 direct/indirect, 128–255 indirect) and AUXILIARY RAM (0–255 indirect only), enabling efficient data movement via MOVX instructions without port side effects.

It features dual serial interfaces: SIO0 as standard UART and SIO1 as CAN transceiver with CTX0/CTX1 differential transmitter outputs and CRX0/CRX1 differential receiver inputs. Power reduction modes include Idle, Power-down, and CAN Sleep, controlled by PCON and enabled via EW pin - all operating within −40 °C to +85 °C temperature range at 1.2–16 MHz clock frequency.

Pinout & Package

Package: PLCC68 (SOT188-2), plastic leaded chip carrier with 68 leads, suitable for surface-mount reflow or wave soldering per Philips specification.

Pin/Terminal	Circuit Role	Design Meaning
VDD (Pin 2)	Digital power supply	+5 V supply for CPU, timers, I/O ports, and digital logic; decoupling required near pin.
VSS (Pin 35)	Digital ground	Reference return for digital circuitry; separate from AVSS to minimize noise coupling into analog subsystem.
AVDD (Pin 61)	Analog power supply	+5 V dedicated supply for ADC, CAN receiver, and internal reference; must be filtered independently.
AVSS (Pin 60)	Analog ground	Ground reference for ADC, CAN receiver, and REF output; routed separately from digital ground.
REF (Pin 55)	1/2 AVDD reference	Output of internal voltage divider; used as ADC reference when internal ref selected (CR.5 = 1); requires ≥10 nF capacitor to AVSS.
CTX0 / CTX1 (Pins 23/24)	CAN transmitter outputs	Differential outputs driving CAN bus; floating during CAN reset; require external termination resistors (120 Ω).
CRX0 / CRX1 (Pins 56/57)	CAN receiver inputs	Differential inputs sensing bus state; CRX0 > CRX1 = recessive (logic 1), CRX0 < CRX1 = dominant (logic 0).
PWM0 / PWM1 (Pins 4/5)	PWM output channels	Push-pull outputs not shared with other functions; support constant HIGH/LOW when loaded with 00H/FFH respectively.
STADC (Pin 3)	ADC start trigger	Rising-edge sensitive input to initiate conversion; also supports software start via ADCS bit in ADCON register.
EW (Pin 6)	Watchdog enable	Active-HIGH input enabling WDT (T3) and disabling Power-down mode; must not float - tie to VDD or controlled logic.
RST (Pin 15)	Reset input/output	Asynchronous active-HIGH input; also outputs reset pulse on T3 overflow or CAN wake-up from Power-down.
XTAL1 / XTAL2 (Pins 34/33)	Oscillator interface	Connects to crystal (1.2–16 MHz) or external clock source; XTAL2 is oscillator output, XTAL1 is input.

Key Features

Feature	Design Value
Integrated CAN 2.0A Controller	Eliminates need for external CAN transceiver (e.g., PCA82C200), reduces BOM count and PCB area while enabling deterministic bus arbitration and error handling.
DMA-Assisted CAN Buffer Transfer	Enables automatic movement of CAN transmit/receive data between on-chip message buffers and internal RAM without CPU intervention, freeing cycles for application tasks.
Dual Independent PWM Channels	Supports motor control or LED dimming with precise duty-cycle resolution (1/255 steps) and configurable frequency range - no timer resource contention between channels.
10-Bit ADC with 8 Analog Inputs	Provides high-resolution sensor interfacing directly on Port 5; internal 1/2 AVDD reference ensures stable conversion across supply variations.
Enhanced Timer T2 Architecture	Combines four capture latches and three compare registers in one 16-bit timer, enabling complex event timing, pulse measurement, and waveform generation in real-time systems.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller-with-integrated-CAN applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
NXP SJA1000T	Standalone CAN controller (no MCU core); requires external 80C51 or compatible host processor.	Used where existing MCU architecture must be retained and CAN functionality added externally.	Select when upgrading legacy 80C51 designs with minimal PCB changes but accepting higher component count and interconnect latency.
Infineon C505CA	8-bit C505 core (not 80C51 compatible); 32 kB ROM, 2 kB RAM, CAN 2.0B, but no integrated ADC or PWM.	Targets high-reliability automotive powertrain applications requiring extended temperature range (−40 °C to +125 °C).	Select when CAN 2.0B frame format and extended temp operation are mandatory, and external ADC/PWM ICs are acceptable.

Compared with NXP SJA1000T and Infineon C505CA, the P80C592FFA/00,512 uniquely integrates 80C51 compatibility, on-chip CAN 2.0A, 10-bit ADC, and dual PWM in a single PLCC68 package - offering lowest system-level BOM cost and deterministic timing for mid-tier automotive and industrial CAN nodes.

FAQ

What is the maximum clock frequency supported by the P80C592FFA/00,512?

The P80C592FFA/00,512 supports a maximum clock frequency of 16 MHz, as specified in the Philips datasheet Section 1. This enables a machine cycle time of 0.75 µs and supports real-time CAN communication at up to 1 Mbit/s. Operation at lower frequencies (down to 1.2 MHz) is also supported for low-power applications.

Does the P80C592FFA/00,512 include on-chip program memory?

Yes, the P80C592FFA/00,512 includes 16 kbytes of on-chip ROM, as confirmed in Section 1 "Features" and Section 7.1 of the Philips datasheet. It is the ROM-less variant of the P8xC592 family - distinct from the P83C592 which includes mask-programmed ROM. External program memory expansion up to 64 kbytes is supported via the EA pin and P0/P2 bus.

How many analog input channels does the ADC in the P80C592FFA/00,512 support?

The P80C592FFA/00,512 integrates a 10-bit ADC with eight analog input channels (ADC0–ADC7), mapped exclusively to Port 5 pins as described in Section 10 and Table 6 of the datasheet. These inputs are multiplexed and selectable via AADR2–AADR0 bits in the ADCON register.

What is the function of the EW pin on the P80C592FFA/00,512?

The EW (Enable Watchdog) pin (Pin 6) on the P80C592FFA/00,512 serves two critical functions: it enables the on-chip Watchdog Timer T3 when driven HIGH, and simultaneously disables the Power-down mode. As stated in Table 1, this pin must not be left floating and should be tied to VDD or actively controlled in system design.

Is the P80C592FFA/00,512 pin-compatible with other members of the P8xC592 family?

Yes, the P80C592FFA/00,512 shares identical PLCC68 (SOT188-2) pinout with P83C592FFA/00,512 and P80C592FHA variants, as confirmed in Section 3 "Ordering Information" and Figure 3 of the datasheet. Differences lie only in ROM presence (P80C vs P83C) and temperature grade (FFA = −40 °C to +85 °C), not pin assignment or electrical behavior.
