Product Overview
P89V664FBC is an EOL 8‑bit 80C51 microcontroller from NXP. It integrates 64 KB Flash and 2 KB RAM, with dual I²C‑bus, SPI and enhanced UART interfaces. Supporting ISP / IAP in‑circuit programming, this industrial‑grade LQFP‑44 device is mainly used for legacy‑equipment maintenance and BOM replacement.
Core Advantages
Dual‑Clock 80C51 Core
12‑clock and 6‑clock(X2) operation modes, up to 40 MHz maximum frequency for improved throughput.
ISP & IAP Flash Capability
64 KB Flash with 128‑byte page erase. UART‑ISP enables in‑circuit programming; IAP supports runtime non‑volatile parameter storage.
Comprehensive On‑Chip Peripherals
Dual I²C‑bus, SPI, PCA with PWM function, three 16‑bit timers and 36 GPIO pins for diverse embedded requirements.
Industrial‑Grade Reliability
Built‑in WDT, POR and LVD circuits; operating temperature ‑40℃ ~ +85℃ for noisy industrial environments.

Frequently Asked Questions
Q1: What are key features of P89V664FBC?
A: EOL NXP 80C51 8‑bit MCU with 64KB Flash, 2KB RAM, dual I²C‑bus, SPI. Supports UART‑based ISP / IAP in‑system programming.
Q2: Does it support 6‑clock(X2) high‑speed mode?
A: Yes. 12‑clock max 40MHz; 6‑clock(X2) max 20MHz for higher instruction throughput.
Q3: What do suffix FBC / FBA stand for?
A: FBC = TQFP‑44(LQFP‑44),‑40~+85℃ industrial grade; FBA = PLCC‑44 industrial version. Different packages, not direct drop‑in replacement.
Q4: Difference between P89V660 / P89V662 / P89V664?
A: Only Flash size differs: P89V660(16KB), P89V662(32KB), P89V664(64KB). Pin‑to‑pin compatible, swap if flash capacity meets your project.
Q5: Can P89V664FBC be used for new‑product design?
A: Not recommended. It is NXP EOL / Obsolete. Intended only for legacy‑equipment repair and BOM spare replacement.
Q6: What package is P89V664FBC?
A: TQFP‑44 (LQFP‑44), 10×10 mm body, SMD surface‑mount package.
Q7: Are there pin‑compatible drop‑in alternatives?
A: No fully pin‑to‑pin compatible modern substitute. Alternative 8051‑core MCUs require hardware modification.
Q8: What are ISP and IAP functions?
A: ISP: Flash programming over UART without external programmer. IAP: runtime flash erase/write for parameter storage, page size 128‑byte.
Q9: How can I get datasheet and volume pricing?
A: Submit quick‑inquiry form for datasheet, ISP guide, stock status and bulk quotation.
