Product details
Overview
P89LPC936FA,529 from NXP Semiconductors is a 8-bit accelerated two-clock 80C51 microcontroller with 16 kB byte-erasable flash code memory, dual 8-bit ADCs (ADC0/ADC1), 512-byte on-chip data EEPROM, and Capture/Compare Unit (CCU) for PWM and input capture. It operates from 2.4 V to 3.6 V with 5 V-tolerant I/O pins and targets embedded control in industrial sensors and low-power instrumentation.
For engineers reviewing the P89LPC936FA,529 datasheet, P89LPC936FA,529 pinout, P89LPC936FA,529 application, or P89LPC936FA,529 equivalent, key selection criteria include its 16 kB flash sector size (2 kB), dual ADC support (AD00–AD03 and AD10–AD13), CCU-enabled PWM generation, 28-pin PLCC package with 26 usable I/Os, and integrated 512-byte auxiliary RAM - all critical for firmware-upgradable sensor nodes and compact motor-control interfaces.
Technical Context
The P89LPC936FA,529 implements an enhanced 80C51 core executing instructions in 2–4 clocks at up to 18 MHz, delivering six times the throughput of standard 80C51 devices. Its architecture integrates dual 8-bit A/D converters with independent channel sets (ADC0: AD00–AD03; ADC1: AD10–AD13), analog comparators (CMP1/CMP2), and a dedicated Capture/Compare Unit supporting four output compare channels (OCA–OCD) and two input capture inputs (ICA/ICB).
It features a configurable on-chip oscillator (20 kHz–18 MHz), fractional baud rate UART, 400 kHz I²C bus, SPI interface, and a 23-bit system timer usable as RTC. Power management includes idle mode, two power-down modes (typical 1 μA total current), and brownout detect with interrupt option - enabling robust operation in battery-powered edge devices.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| P89LPC935FA | 8 kB flash (vs. 16 kB), same 28-pin PLCC package, identical peripheral set (dual ADC, CCU, EEPROM) | Lower code density margin; suitable for simpler control tasks without OTA updates or large protocol stacks | Select when firmware footprint <100 KB and no future feature expansion is planned |
| EFM8BB52F16G-A-QFP28 | Silicon Labs EFM8 Busy Bee MCU: 16 kB flash, 2.25 V–3.6 V, 50 MHz 8051 core, but no integrated EEPROM or analog comparators | Lacks on-chip EEPROM and comparator-based fast trip; requires external components for data retention and overcurrent protection | Choose only if higher CPU speed (50 MHz) and USB interface outweigh loss of analog integration and EEPROM |
Compared with P89LPC935FA, the P89LPC936FA,529 provides double flash capacity for complex control algorithms and firmware resilience; versus EFM8BB52F16G-A-QFP28, it retains critical analog integration (EEPROM, comparators, dual ADCs) in a single die - reducing BOM count and PCB area in cost-sensitive industrial modules.

FAQ
What is the maximum operating frequency of the P89LPC936FA,529?
The P89LPC936FA,529 supports a maximum CPU clock frequency of 18 MHz when using the external crystal/resonator or internal RC oscillator. At this frequency, instruction cycle times range from 111 ns to 222 ns - six times faster than a standard 80C51 running at the same clock rate. The configurable oscillator allows selection of frequencies from 20 kHz to 18 MHz via flash configuration bits.
Does the P89LPC936FA,529 support in-system programming (ISP)?
Yes, the P89LPC936FA,529 supports In-System Programming (ISP) via its UART interface, allowing firmware updates while the device is soldered into the target application. This capability eliminates the need for socketed programming and enables field upgrades. ISP entry is triggered by holding P1.5 (RST) low during power-up while VDD rises through the valid operating range.
How many analog-to-digital converter channels does the P89LPC936FA,529 have?
The P89LPC936FA,529 integrates two independent 8-bit ADC subsystems: ADC0 with four channels (AD00–AD03) and ADC1 with four channels (AD10–AD13), for a total of eight analog inputs. Both ADCs share the same reference voltage and support simultaneous or interleaved sampling, making the P89LPC936FA,529 suitable for multi-sensor monitoring applications.
What package type is used for the P89LPC936FA,529?
The P89LPC936FA,529 is supplied in a 28-pin PLCC (plastic leaded chip carrier) package, designated SOT261-2. This surface-mount package measures 11.5 × 11.5 × 4.0 mm with 1.27 mm lead pitch and provides 26 usable I/O pins when on-chip oscillator and reset options are enabled - ideal for compact industrial control PCBs.
Is the P89LPC936FA,529 pin-compatible with other members of the LPC93x family?
The P89LPC936FA,529 shares identical pinout and package dimensions with P89LPC935FA (PLCC28), including function mapping for all 28 pins. However, it is not pin-compatible with TSSOP28 or HVQFN28 variants (e.g., P89LPC936FDH or P89LPC936FHN) due to differing pin assignments and thermal pad requirements - board layout must match the specific package variant ordered.
