Detailed Description

Intel N80C152JB / LN80C152JB are legacy 8-bit controller-class Specialized ICs from the MCS‑51 family, widely used in embedded control and communications systems

They support external program/data memory, rich I/O, multiple timers/interrupts, and robust serial connectivity typical of 8051‑class designs

The LN80C152JB variant is commonly associated with low‑power/low‑voltage grading in Intel naming; JB typically denotes PLCC packaging

Category: Integrated Circuits (ICs) / Specialized ICs

Available stock quantity: 1102 units

Date code: mixed/assorted (+). Contact us for exact DC per lot

Key Features

Mature 8051‑compatible core architecture for easy development and maintenance

External program/data memory interface for flexible system design

Multiple timers/counters and a vectored interrupt system for precise control

Full‑duplex serial interface(s) common to 8051 family; enhanced communications are typical for 80C152 variants

Broad I/O port availability for direct peripheral control

Watchdog/supervisory functions are common on many 80C152 revisions

5 V logic operation typical for the family; TTL/CMOS compatible I/O

Wide ecosystem of compilers, debuggers, and programmers due to 8051 heritage

Key Advantages

Proven, stable platform for sustaining legacy designs with minimal requalification

Large developer community and abundant documentation/training resources

Easy migration paths to modern 8051‑compatible MCUs when needed

Long‑term serviceability in installed industrial/communications equipment

Strong availability of pin‑compatible or software‑compatible alternatives from multiple vendors

Packaging

Type: PLCC (JB suffix in Intel part naming commonly indicates Plastic Leaded Chip Carrier)

Material: Molded plastic carrier with J‑leads designed for socket or PCB mounting

Size: Square PLCC body, approximately low‑profile; typical PLCC pitch is 1.27 mm (confirm exact body size/pitch in the datasheet)

Pin configuration: High pin‑count PLCC with J‑leaded pins around the perimeter; consult datasheet for exact pin count and pinout

Thermal characteristics: Suitable for commercial temperature ranges; industrial‑temp variants may exist; rely on PCB copper area and airflow for heat dissipation

Electrical properties: 5 V operation is typical for 80C‑series; I/O levels compatible with TTL/CMOS; clock frequency depends on the specific speed grade. Verify exact ratings in the datasheet

Package / Case code provided: 1503 (contact us for mechanical drawing confirmation and packing details such as trays or tubes)

Lifecycle

Status: Legacy/NRND in many regions; often considered discontinued or limited availability from the original manufacturer

Recommended path: Sustainment purchases for existing designs; consider vetted 8051‑family alternatives for new designs

Potential equivalent or alternative models (verify pinout and feature match before substitution):

- NXP/Philips: P80C51/P89C51 family, 80C552/80C552‑compatible devices for enhanced serial features

- Microchip/Atmel: AT89C51, AT89S51/AT89S52 series (software‑compatible 8051 cores)

- Silicon Labs: C8051F series (enhanced 8051 with integrated peripherals; not pin‑compatible but strong migration path)

- Infineon: XC800/8051‑based devices

- STC: STC12/STC15 series (high‑speed 8051‑compatible MCUs)

- Nuvoton/Winbond: W77E/W78E series (8051‑compatible)
