|---|---|
| Manufacturer | Intel Corporation (Discontinued CAN Controller) |
| Category | Integrated Circuits (ICs) > Interface – Controllers / CAN Controllers |
| Description | Standalone CAN Controller, CAN Protocol 2.0B Active, Flexible Microprocessor Interface, 15 Message Objects, 44-QFP Package. |
| Stock Status | In Stock |
| Origin | Original Factory |
Product Overview
The AS82527 is a standalone CAN communication controller developed by Intel. It acts as an interface between main MCUs and CAN buses, fully supporting CAN 2.0A/2.0B with transmission speed up to 1 Mbps. Equipped with 15 independent message objects and flexible 8/16-bit parallel bus interface, it offloads message filtering and error processing for automotive ECUs, industrial equipment and avionics. This model is discontinued by Intel; our stock is only for equipment maintenance replacement.
Core Advantages
Full CAN 2.0B Protocol Support
Compatible with 11-bit standard frames and 29-bit extended frames, built-in CRC verification and bit stuffing to ensure stable data transmission on noisy buses.
15 Independent Message Buffers
15 configurable transmit/receive message objects with programmable filter masks to reduce unnecessary CPU interrupts.
Universal Parallel Bus Interface
Works with 8-bit / 16-bit multiplexed or non-multiplexed MCUs including 80C51, 68HC and ARM series.
Comprehensive Hardware Error Detection
Built-in hardware monitors bit, stuffing, ACK and CRC errors, with transmit & receive error counters to isolate bus faults automatically.

Frequently Asked Questions
Q1: What is the function of AS82527 in CAN network?
A: It is an independent CAN controller, connecting main MCU and CAN transceiver, and automatically completes CAN layer 2 framing, error detection and message filtering.
Q2: What’s special about the 15th message object?
A: It adopts double-buffer receiving design to avoid data loss when continuous high-priority messages are received.
Q3: Can AS82527 connect to 3.3V MCU directly?
A: No, it works at 5V. Level shifters are required to connect with 3.3V chips to prevent pin damage.
Q4: What are the merits of 44-QFP package?
A: J-type pins resist thermal shock; it supports direct PCB welding or socket plugging, convenient for maintenance and prototype testing.
Q5: Is AS82527 still in mass production?
A: Intel has discontinued production, we only supply original stock for equipment maintenance and replacement.
Q6: What is the maximum baud rate supported by this chip?
A: Up to 1Mbps, suitable for automotive and high-speed industrial CAN bus systems.
Q7: Does AS82527 support RoHS lead-free standard?
A: Original Intel version is leaded; Rochester reproduced G suffix models meet RoHS requirements.
Q8: What crystal frequency can be matched?
A: The maximum input crystal oscillator frequency is 16 MHz, do not use 24MHz crystal.
