Product Overview
MT90826AL is a high‑density non‑blocking TDM digital switch IC from Microchip (formerly Zarlink / Mitel). It supports 4096×4096 switching channels with 16‑in /16‑out serial ST‑BUS streams up to 16.384Mbps. Operating at 3.3V with 5V‑tolerant I/O, this 160‑MQFP industrial‑grade chip is widely used for telecom switching, media gateway and wireless base station equipment, now EOL obsolete device.
Core Advantages
4096×4096 Non‑blocking Matrix
Full non‑blocking time‑space switching for 4K channels, avoids channel conflict under heavy telecom traffic load.
Multi‑Rate ST‑BUS Interface
Supports 2.048 / 4.096 / 8.192 /16.384 Mbps serial rate, compatible with ST‑BUS / GCI telecom backplane.
Per‑channel Programmable Control
8‑/16‑bit MCU parallel bus, supports per‑channel configuration, frame offset delay measurement and bit‑error monitoring.
Industrial‑grade & JTAG Debug
‑40℃~+85℃ working range, 3.3V low‑power CMOS, IEEE‑1149.1 JTAG test port for board debugging.

Frequently Asked Questions
Q1: What is the switching capacity of MT90826AL?
A: It features a 4096×4096‑channel non‑blocking time‑space switching matrix with 16 input and 16 output serial streams.
Q2: What serial bus standards does MT90826AL support?
A: Compatible with ST‑BUS / GCI, data rates: 2.048 / 4.096 / 8.192 / 16.384 Mbps, supports split‑rate mixed‑rate switching.
Q3: What package is MT90826AL?
A: MT90826AL: 160‑MQFP (28×28 mm); pin‑compatible variant MT90826AG: 160‑PBGA package.
Q4: Difference between MT90826AL and MT90826AL1?
A: Fully pin‑to‑pin functional compatible. MT90826AL: tin‑lead terminals; MT90826AL1: matte‑tin lead‑free, RoHS compliant.
Q5: Can MT90826AL directly replace MT90826AG?
