Product details

Overview

P80C562EBA/02,512 from NXP Semiconductors (formerly Philips) is an 8-bit CMOS microcontroller based on the 80C51 architecture, featuring 8 kB mask-programmable ROM, 256 bytes RAM, dual 8-bit PWM outputs, an 8-channel 8-bit ADC, and six I/O ports - designed for automotive engine and gearbox control applications operating at 0 to +70°C.

For engineers reviewing the P80C562EBA/02,512 datasheet, P80C562EBA/02,512 pinout, P80C562EBA/02,512 application, or P80C562EBA/02,512 equivalent, this page delivers verified technical context, package mapping, functional pin roles, real-world use cases in automotive subsystems, and validated alternative parts with documented differences in memory, ADC, and timer capabilities.

Technical Context

The P80C562EBA/02,512 integrates a standard 80C51 CPU core with architectural extensions including a third 16-bit timer (T2) with four capture latches and three compare registers, enabling precise event timing and pulse-width modulation synchronization. Its ADC supports eight analog inputs with dedicated AVDD/AVSS and AVREF+/AVREF− pins for noise-immune conversion.

It implements two software-selectable low-power modes: Idle mode halts the CPU while preserving RAM, timers, UART, and interrupt operation; Power-down mode retains RAM but stops the oscillator and all peripherals. The device uses a single-phase clock input (XTAL1/XTAL2) and supports 3.5–16 MHz crystal or external clock sources.

Key Specifications

Parameter	Value and Actual Design Meaning
CPU Core	80C51-compatible 8-bit architecture with full instruction set compatibility and 100+ instructions.
ROM Size	8 kbytes mask-programmable ROM - fixed firmware storage; no reprogramming capability.
RAM Size	256 bytes internal RAM - sufficient for real-time control stacks and register banks without external expansion.
ADC Resolution	8-bit SAR ADC with 8 multiplexed analog inputs - supports sensor interfacing with 18 µs conversion time at 16 MHz.
PWM Outputs	Two independent 8-bit PWM channels (PWM0/PWM1) with shared prescaler and 255-step duty control - suitable for motor drive or lamp dimming.
Timer Resources	Three 16-bit timers: T0/T1 (standard 80C51), plus T2 with capture/compare logic - enables high-precision timing, edge detection, and waveform generation.
Operating Temp	0°C to +70°C - commercial-grade temperature range confirmed for P80C562EBA variant.
Oscillator Range	3.5 MHz to 16 MHz - supports both low-power crystal and high-speed system clocking.

Pinout & Package

Package: PLCC68 (SOT188-2), 68-pin plastic leaded chip carrier with J-lead configuration - compatible with surface-mount reflow and wave soldering per Philips Soldering Handbook Section 23.

Pin/Terminal	Circuit Role	Design Meaning
P0.0/AD0 – P0.7/AD7	Multiplexed address/data bus (lower byte)	Shared AD0–AD7 lines for external memory expansion; requires external latch (ALE-controlled) during access.
P2.0/A8 – P2.7/A15	High-order address bus	Provides A8–A15 for 64 kB external program/data memory addressing when EA = LOW or address > 8191.
P5.0/ADC0 – P5.7/ADC7	Analog input channels	Dedicated 8-channel analog inputs with hysteresis; used exclusively as inputs - no digital output capability.
PWM0 / PWM1	Pulse-width modulated outputs	Push-pull drivers; independent 8-bit duty control via PWM0/PWM1 SFRs - no shared function or port contention.
STADC	Hardware ADC start trigger	Rising-edge sensitive input; initiates conversion alongside software ADCS bit - enables synchronized sampling.
EW	Watchdog enable / Power-down disable	Active-HIGH signal that enables watchdog timer and prevents entry into Power-down mode - must not float.
AVDD / AVSS	Analog power supply rails	Separate +5 V and ground for ADC circuitry - isolates analog reference from digital noise sources.
AVREF+ / AVREF−	ADC reference voltage terminals	Accept external precision reference (e.g., bandgap or resistor divider); defines full-scale ADC range.

Key Features

Feature	Design Value
Third 16-bit timer with capture/compare	T2 provides four 16-bit capture latches and three compare registers - enables precise measurement of pulse width, period, and phase difference.
Dual independent PWM outputs	PWM0 and PWM1 share prescaler but operate independently - allows simultaneous control of two actuators with distinct duty cycles.
Eight-channel 8-bit ADC with dedicated analog IO	ADC inputs mapped to Port 5 only; hysteresis prevents excessive current draw from analog signals - improves robustness in noisy automotive environments.
Full-duplex UART compatible with 80C51	Standard RXD/TXD pins with identical framing and baud rate generation - ensures drop-in replacement in legacy 8051-based communication designs.
Two reduced-power modes (Idle/Power-down)	Idle preserves RAM, timers, UART, and interrupts; Power-down retains RAM only - enables battery-conscious operation in ECU sleep states.
On-chip Watchdog Timer (T3)	Independent 8-bit counter with overflow reset - prevents system lockup in safety-critical automotive functions without external supervision.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 8-bit microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
P83C562EBA/02,512	8 kB mask-ROM, same PLCC68 package and pinout, identical ADC/PWM/timer architecture	ROM-coded version - firmware fixed at manufacture; no field reprogramming	Select when production firmware is finalized and long-term code immutability is required.
AT89C51RC2-UM	8 kB Flash ROM, 512 B RAM, same 8051 core but no T2 capture/compare or STADC pin; ADC not integrated	Lacks dedicated automotive peripherals - requires external ADC and capture logic for ECU use	Choose for prototyping or firmware updates; avoid where T2 capture or hardware ADC start is mandatory.

Compared with P80C562EBA/02,512, the P83C562EBA/02,512 offers identical functionality with mask-ROM instead of ROMless implementation, while the AT89C51RC2-UM trades integrated peripherals for field-upgradable Flash but removes critical automotive features like T2 capture and STADC-triggered conversion.

FAQ

What is the maximum oscillator frequency supported by the P80C562EBA/02,512?

The P80C562EBA/02,512 supports an oscillator frequency range of 3.5 MHz to 16 MHz, as specified in the Philips datasheet Section 16 and AC Characteristics table. At 16 MHz, instruction execution times are optimized: 58% of instructions complete in 0.75 µs and 40% in 1.5 µs. The P80C562EBA/02,512 uses a single-phase clock input via XTAL1/XTAL2 pins and does not require external clock conditioning beyond standard crystal load capacitance.

Does the P80C562EBA/02,512 include an integrated analog-to-digital converter?

Yes, the P80C562EBA/02,512 includes an 8-bit successive-approximation ADC with eight multiplexed analog inputs (ADC0–ADC7) routed exclusively to Port 5. Conversion time is 24 machine cycles - 18 µs at 16 MHz - and is controlled via the ADCON register. Dedicated AVDD, AVSS, AVREF+, and AVREF− pins ensure analog signal integrity separate from digital power domains.

How many timer/counter modules does the P80C562EBA/02,512 have, and what are their key capabilities?

The P80C562EBA/02,512 contains three 16-bit timer/event counters: Timer 0 and Timer 1 (fully compatible with standard 80C51 modes), plus Timer 2 (T2) - an enhanced module with four 16-bit capture latches and three compare registers. T2 supports input capture on rising edges (CT0I–CT3I), compare-match output (CMSR0–CMSR5), and toggle/enable logic (CMT0/CMT1), making it ideal for engine timing and PWM synchronization.

What power-saving modes are available on the P80C562EBA/02,512, and how do they differ?

The P80C562EBA/02,512 supports two software-selectable low-power modes: Idle mode halts the CPU while maintaining RAM, timers, serial port, and interrupt functionality; Power-down mode retains RAM contents but stops the oscillator and disables all peripherals. Entry is controlled via the Power Control Register (PCON), and the EW pin must be held HIGH to prevent accidental Power-down activation.

Is the P80C562EBA/02,512 pin-compatible with other members of the P8xC562 family?

Yes, the P80C562EBA/02,512 is pin-compatible with all P8xC562 variants in the PLCC68 (SOT188-2) package, including P83C562EBA/02,512 and P80C562EFA/02,512. Differences lie in ROM content (mask vs. ROMless), temperature grade (0–70°C vs. −40–85°C), and ordering codes - not pin assignment or electrical behavior. Pin functions, drive strength, and timing parameters remain consistent across the family.
