Product details
Overview
ADM8262-AC-T-1 from Infineon is a single-chip 802.11a/b/g WLAN MAC and baseband processor (BBP) controller for PCI, mini-PCI, and CardBus interfaces. It integrates hard-wired WEP/TKIP/AES-CCM security per 802.11i, supports infrastructure/ad-hoc modes under DCF, and delivers full AP/STA/STA-converter/AP repeater functionality with antenna diversity support. Used in embedded wireless NICs and access point modules.
For engineers reviewing the ADM8262-AC-T-1 datasheet, ADM8262-AC-T-1 pinout, ADM8262-AC-T-1 application, or ADM8262-AC-T-1 equivalent, key selection factors include integrated MAC+BBP architecture, 128-pin LQFP package, 32-bit PCI interface compliance, on-chip 3.3 V to 1.8 V regulator control, and native support for Windows Native WiFi, Linux, Win CE, and Mac OS.
Technical Context
The ADM8262 implements a state-machine-based WMAC core eliminating external memory requirements, and embeds dedicated hardware accelerators for 802.11e QoS, 802.11h TPC/spectrum management, and 802.11d country-code enforcement. Its BBP handles OFDM (802.11a) and DSSS/CCK (802.11b/g) modulation schemes in a unified pipeline.
It interfaces directly with dual-band RF front ends-including Infineon's own Dual Band RF/PA solutions-and provides GPIO, LED, serial EEPROM, and regulator control blocks. The chip operates from a 3.3 V supply with 5 V/3.3 V I/O tolerance and uses a 0.18 µm CSM CMOS process.

Equivalent & Alternatives
The following parts are listed as comparable options for similar WLAN MAC+BBP controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Marvell 88W8361 | PCI Express interface instead of parallel PCI; requires different host bridge and driver stack. | Targeted at newer embedded platforms with PCIe lanes; lacks native CardBus support. | Select when migrating to PCIe-based designs and requiring higher bandwidth than PCI 33 MHz. |
| Realtek RTL8185L | Integrated RF transceiver (2.4 GHz only); no dual-band capability; uses external EEPROM for calibration data. | Suitable for cost-sensitive 802.11b/g-only endpoints; not compliant with 802.11a or dual-band operation. | Choose only for single-band 2.4 GHz client applications where RF integration reduces footprint more than dual-band flexibility. |
Compared with Marvell 88W8361 and Realtek RTL8185L, the ADM8262-AC-T-1 uniquely combines parallel PCI/mini-PCI/CardBus compatibility, dual-band RF readiness, and hardware-enforced 802.11i security-all in one LQFP package-making it optimal for legacy and hybrid wireless infrastructure upgrades.

FAQ
Does ADM8262-AC-T-1 support 802.11n?
No. The ADM8262-AC-T-1 implements only IEEE 802.11a/b/g standards. It does not include MIMO, 40 MHz channels, or HT modulation required for 802.11n. Its PHY layer is limited to OFDM (6–54 Mbps) and DSSS/CCK (1–11 Mbps) rates.
Is an external serial EEPROM required for operation?
Yes. The ADM8262-AC-T-1 requires an external serial EEPROM (typically 2 Kbit or larger) to store MAC address, regulatory domain settings, RF calibration data, and optional firmware patches. The chip provides dedicated I²C-compatible interface pins for this purpose.
What thermal management is recommended for continuous AP-mode operation?
For sustained AP operation at full transmit power, a minimum 25 mm² copper pour under the LQFP body with ≥4 thermal vias to inner ground planes is recommended. Ambient temperature must remain ≤70°C; junction temperature must not exceed 110°C per Infineon's published thermal derating curves.
Can ADM8262-AC-T-1 operate in both infrastructure and ad-hoc modes simultaneously?
No. The device supports infrastructure, ad-hoc, AP, STA-converter, and AP repeater modes-but only one mode at a time. Mode selection is configured via registers during initialization and cannot be dynamically switched without full reset and reinitialization.
