Product details
Overview
P89LPC983FDH,529 from NXP Semiconductors is an 8-bit accelerated two-clock 80C51 microcontroller in TSSOP28 package, featuring 4 kB byte-erasable flash memory, 256-byte RAM, 4-channel 10-bit ADC with window comparator, five 16-bit timers, and integrated I²C, SPI, and enhanced UART interfaces. It operates from 2.4 V to 5.5 V and supports in-system programming for embedded control in industrial sensors and low-power instrumentation.
For engineers reviewing the P89LPC983FDH,529 datasheet, P89LPC983FDH,529 pinout, P89LPC983FDH,529 application, or P89LPC983FDH,529 equivalent, key selection criteria include its 4-channel ADC configuration (vs. 8-channel on P89LPC985), TSSOP28 pin mapping with ADC inputs on P0.1–P0.4 and P1.7, internal RC oscillator accuracy (±1 %), and support for In-Application Programming (IAP) of flash memory.
Technical Context
The P89LPC983FDH,529 implements a high-performance 80C51 core executing instructions in two to four clocks-six times faster than standard 80C51 at same frequency-with CPU clock options including internal RC (7.373 MHz ±1 %), watchdog oscillator (400 kHz/25 kHz), or external crystal up to 18 MHz. Its system timer combines a 7-bit prescaler and programmable 16-bit counter for real-time clock functionality.
It integrates dual analog comparators with selectable inputs and reference, port remap capability for UART/I²C/SPI signals, and configurable I/O modes (quasi-bidirectional, open-drain, push-pull). Power management includes idle and two power-down modes, with typical total power-down current of 1 μA when voltage comparators are disabled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | Accelerated two-clock 80C51 CPU delivering 111–222 ns instruction cycle time at 18 MHz - enables higher throughput with lower EMI vs. legacy 8051. |
| Flash Memory | 4 kB byte-erasable flash organized in 1 kB sectors and 64-byte pages - supports non-volatile data storage via single-byte erase. |
| ADC | 4-input multiplexed 10-bit ADC with window comparator interrupt - enables threshold-based sensor monitoring without host CPU polling. |
| Timers | Five 16-bit counter/timers (T0–T4); each configurable as PWM output or port toggle on overflow - provides flexible timing and signal generation for motor control or LED dimming. |
| Oscillator | Internal RC oscillator calibrated to ±1 % at 7.373 MHz with clock doubler option - eliminates need for external crystal in cost-sensitive applications. |
| Supply Range | 2.4 V to 5.5 V operation - supports direct interface with 3.3 V and 5 V logic systems and battery-powered operation down to 2.4 V. |
| Power Modes | Idle mode and two power-down modes; wake-up from power-down via LOW interrupt input - extends battery life in intermittent-sensing applications. |
Pinout & Package
TSSOP28 package (SOT361-1), 4.4 mm body width, 28-pin surface-mount with 23 minimum I/O pins and up to 26 I/Os using on-chip oscillator and reset options.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P0.0/CMP2/KBI0/SPICLK | Port 0 bit 0 / Comparator 2 output / Keypad input 0 / SPI clock | Multi-function pin supporting SPI master/slave clock, analog comparator output, or keypad scan - requires SFR configuration for mode selection. |
| P0.1/CIN2B/KBI1/AD00 | Port 0 bit 1 / Comparator 2 positive input B / Keypad input 1 / ADC channel 0 | Analog input for ADC0 channel 0 and comparator; Schmitt-triggered for noise immunity in keypad or sensor interface. |
| P0.2/CIN2A/KBI2/AD01 | Port 0 bit 2 / Comparator 2 positive input A / Keypad input 2 / ADC channel 1 | Second analog input pair for differential comparator use or independent ADC sampling - supports simultaneous analog sensing. |
| P0.3/CIN1B/KBI3/AD02/T2 | Port 0 bit 3 / Comparator 1 positive input B / Keypad input 3 / ADC channel 2 / Timer 2 input | Shared ADC/comparator/timer function enables synchronized event capture and analog measurement - high-current sourcing (20 mA) supports direct LED drive. |
| P0.4/CIN1A/KBI4/AD03 | Port 0 bit 4 / Comparator 1 positive input A / Keypad input 4 / ADC channel 3 | Completes 4-channel ADC set; paired with P0.3 for full analog front-end on Port 0 - no external mux required for basic sensor arrays. |
| P1.5/RST | Port 1 bit 5 / External reset input | Input-only pin; asserts hardware reset on LOW; also initiates ISP mode during power-on - eliminates need for external reset IC. |
| P2.0/AD07/TXD | Port 2 bit 0 / ADC channel 7 / UART transmit | Not used for ADC on P89LPC983 (ADC only on P89LPC985); functions as TXD - pin remap allows UART relocation to avoid routing conflicts. |
| VDD / VSS | Power supply / Ground | Single-supply operation; only VDD and VSS required when internal reset and oscillator selected - minimizes BOM count and PCB area. |
Key Features
| Feature | Design Value |
|---|---|
| In-Application Programming (IAP) | Enables firmware updates while device is running - critical for field-upgradable industrial controllers without service interruption. |
| Configurable port output modes | Quasi-bidirectional, open-drain, push-pull, or input-only per pin - simplifies interface to diverse peripherals (e.g., I²C pull-ups, relay drivers, CMOS logic). |
| Port input pattern match detect | Generates interrupt when Port 0 matches programmable 8-bit pattern - reduces CPU load in keypad scanning or state-change detection. |
| Controlled slew rate outputs | ~10 ns minimum ramp time on all port outputs - lowers EMI emissions to meet Class B compliance without added filtering. |
| Integrated PMU | Automatically adjusts internal regulators in Idle/Power-down modes - achieves 1 μA typical total power-down current without software tuning. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P89LPC985FDH | 8 kB flash, 8-channel 10-bit ADC, auxiliary 256-byte RAM - adds two extra ADC channels (AD04–AD07) and larger code space. | Required for designs needing >4 analog inputs or >4 kB application code; not drop-in due to different ADC pin mapping and memory layout. | Select P89LPC985FDH only if additional ADC channels or flash capacity are confirmed necessary - avoids over-specification and cost premium. |
| P89LPC982FDH | 8 kB flash, no ADC, 256-byte auxiliary RAM - lacks analog front-end but doubles program memory and adds auxiliary RAM. | Suitable for digital-only control tasks (e.g., protocol translation, logic sequencing) where ADC is unnecessary and code size exceeds 4 kB. | Choose P89LPC982FDH when analog sensing is absent and firmware complexity demands >4 kB flash - retains identical pinout and peripheral set except ADC. |
Compared with P89LPC985FDH and P89LPC982FDH, the P89LPC983FDH,529 delivers optimal balance of analog capability (4-channel ADC), compact code footprint (4 kB flash), and TSSOP28 footprint - making it the most cost-effective choice for mid-complexity sensor-control applications without overengineering.
