AT89LP216-20XU Equivalent & Substitute Parts Reference

Part Overview

The AT89LP216-20XU is an 8-bit 8051 89LP microcontroller IC from Microchip Technology, featuring a core speed of 20MHz, 2KB FLASH program memory, and 14 I/O pins, all housed in a 16-TSSOP surface-mount package. With an operating supply voltage of 2.4V to 5.5V and an industrial temperature range of -40°C to 85°C, it is suitable for embedded control applications requiring multiple connectivity and peripheral features. The part is currently obsolete. Identifying substitutes with closely matching electrical, mechanical, and performance characteristics is necessary for ongoing design support and end-of-life management.

Substitute Part Grouping Explanation

Substitution is based solely on matching the key operational and package parameters. Substitute parts are included if they provide:

  • Identical core processor, core size, and speed
  • The same series and family association (89LP)
  • Matching program memory size and RAM size
  • Overlapping operating voltage range and industrial temperature support
  • Equivalent peripherals and connectivity features
  • Matching number of I/O pins
  • Surface-mount package with comparable pin count and footprint
  • Supported compliance and certification requirements

Engineering Selection Recommendations

Selection is permitted strictly based on the product status, RoHS and REACH compliance, and MSL ratings as provided. The main part, AT89LP216-20XU, is obsolete, while the substitute AT89LP216-20SU remains active, offering uninterrupted availability. Both parts are compliant with RoHS and REACH requirements. MSL status is specified for AT89LP216-20XU as level 3 (168 hours); MSL for AT89LP216-20SU is not provided in the input.

Frequently Asked Questions (FAQ)

Q1: Which key parameters determine if AT89LP216-20SU is a suitable substitute for AT89LP216-20XU?
A1: Suitable substitution requires matched core processor, series, memory capacities, speed, voltage range, I/O count, peripherals, connectivity, oscillator type, and surface-mount package with equivalent pin count.

Q2: Are AT89LP216-20XU and AT89LP216-20SU pin-compatible?
A2: Both devices use 16-pin surface-mount packages with matching I/O count, but package dimensions differ (TSSOP vs. SOIC). Compatibility should be confirmed at the mechanical level if fit to an existing board is required.

Q3: What compliance and status factors should be considered in selection?
A3: Product viability is influenced by lifecycle status, RoHS and REACH compliance, and moisture sensitivity. AT89LP216-20XU is obsolete; AT89LP216-20SU is active and compliant to RoHS and REACH as per the input.

Q4: Does substitution affect application performance?
A4: Based on the provided parameters, electrical and functional performance is equivalent. Mechanical differences such as package size should be considered if layout constraints exist.
