Product details
Overview
PCI6515AZHK from Texas Instruments is a single-socket CardBus controller IC with integrated dedicated smart card socket, supporting PCI 2.2 bus interface, 32-bit/33-MHz operation, and dual-function PCI configuration space (Function 0 for CardBus, Function 5 for Smart Card). It implements ExCA-compliant register sets, supports Suspend Mode power management per ACPI 1.0b, and delivers 48-MHz clock generation for CardBus timing.
For engineers reviewing the PCI6515AZHK datasheet, PCI6515AZHK pinout, PCI6515AZHK application, or PCI6515AZHK equivalent, this device is selected for legacy PC Card host designs requiring simultaneous CardBus and ISO 7816 smart card support in a single-chip solution with integrated LDO voltage regulation and hardware-based card insertion/removal detection.
Technical Context
The PCI6515AZHK integrates two independent PCI functions: Function 0 implements a full CardBus bridge with ExCA-compatible socket registers, 16-/32-bit PC Card interface, and programmable I/O/memory windows; Function 5 implements a dedicated ISO 7816-3 smart card controller with T=0/T=1 protocol support, built-in baud rate generator, and smart card power control logic.
It features an integrated low-dropout voltage regulator (LDO-VR) for CardBus VCC supply, supports PCI Bus Lock and SERR# signaling, implements serial EEPROM (I²C) interface for configuration storage, and provides hardware-accelerated card detection, ring indication (RI_OUT), and LED activity indicators - all compliant with PCMCIA r7.1 and PCI Local Bus Specification Rev 2.2.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CardBus + smart card controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PCI6515AIGHK | Same die, different temperature grade (–40°C to +105°C industrial vs. –40°C to +85°C for ZHK) | Required for extended-temperature deployments (e.g., automotive telematics, outdoor kiosks) | Select PCI6515AIGHK when ambient operating temperature exceeds +85°C; otherwise PCI6515AZHK suffices. |
| PCI6520AZHK | Two-socket variant with identical smart card controller and dual CardBus bridges; larger 29 mm × 29 mm BGA | Supports dual PC Card slots (e.g., simultaneous modem + smart card reader) but increases PCB footprint and power draw | Choose PCI6520AZHK only if dual-socket functionality is mandatory; PCI6515AZHK offers lower cost and smaller layout for single-slot systems. |
Compared with PCI6515AIGHK and PCI6520AZHK, the PCI6515AZHK provides optimal balance of industrial temperature margin, single-socket integration, and minimal board area-making it the preferred choice for cost-sensitive, space-constrained embedded hosts requiring exactly one CardBus slot and one smart card interface.

FAQ
What is the primary function of the PCI6515AZHK in a system architecture?
The PCI6515AZHK serves as a dual-function PCI device: Function 0 implements a full CardBus bridge for PC Card peripherals (modems, network adapters), while Function 5 provides a dedicated ISO 7816-3 smart card controller. It replaces discrete bridge + smart card ICs, integrating ExCA-compliant socket registers, LDO regulation, and hardware card detection-all within a single 256-ball BGA. This enables compact, low-power host designs where PCI bus resources must be shared efficiently between legacy expansion and secure credential interfaces.
Does the PCI6515AZHK support both 3.3-V and 5-V smart cards?
Yes, the PCI6515AZHK supports both 5-V and 3-V smart cards via its VSIM output pin, which is programmable through the Smart Card Configuration 1 Register. The device automatically adjusts voltage level and current limits based on card type detection, complies with ISO 7816-3 timing requirements for T=0 and T=1 protocols, and includes short-circuit protection and thermal shutdown. This dual-voltage capability allows seamless interoperability with legacy 5-V banking cards and modern 3-V eID cards without external level-shifting circuitry.
How does the PCI6515AZHK handle power management during CardBus card insertion?
The PCI6515AZHK implements hardware-accelerated power management for CardBus cards using dedicated CD1# and CD2# inputs that trigger immediate socket event interrupts-eliminating software polling. Upon card insertion, it asserts PME# to wake the host from Suspend Mode (ACPI D3), activates the integrated LDO-VR to supply 3.3-V VCC, configures power-switch interface signals (PWR_SW, PWR_EN), and initializes ExCA registers for socket enumeration. All timing meets PCMCIA r7.1 requirements, ensuring reliable hot-plug operation across –40°C to +85°C.
Can the PCI6515AZHK operate without an external serial EEPROM?
Yes, the PCI6515AZHK can operate without an external serial EEPROM. While the I²C interface supports optional EEPROM for storing vendor-specific configuration (e.g., subsystem IDs, GPIO defaults), all essential PCI configuration space values-including Vendor ID (0x104C), Device ID (0xAC15), Class Code (0x068005), and Base Address Registers-are hard-coded in silicon. Default ExCA and smart card register settings are also internally initialized at reset, allowing full functional operation with zero external non-volatile storage-ideal for cost-sensitive or tamper-resistant designs.
What distinguishes the ZHK package suffix in PCI6515AZHK from other variants?
The ZHK suffix denotes a 256-ball plastic BGA package with 17 mm × 17 mm body size and 1.0-mm ball pitch, qualified for industrial temperature operation (–40°C to +85°C). It differs from the GHK variant (same pinout, commercial temperature grade 0°C to +70°C) and the IGHK/IGZHK variants (identical packaging with extended –40°C to +105°C rating). The ZHK variant is optimized for reliability in thermally demanding embedded applications while maintaining full register and timing compatibility with all other PCI6515A family members.
