Product Details

Description



Features:

Intel platform compatability
   -Enables security-enhanced platform infrastructure; facilitates option to remove ISA.
Firmware hub hardware interface mode
   - 5-Signal communication interface supporting  byte-at-a-time reads and writes
   - Register-based read and write protection for each code/data storage block
   -Hardware write protect pins for the top boot block and the remaining code/data storage blocks
   -5 Additional GPIs for platform design flexibility
   - Contains a hardware Random Number Generator (RNG) for enhancing platform security
   -Integrated Command User Interface (CUI) for requesting access to locking, programming, and erasing options. The CUI also handles requestsfor data residing in status, ID, and block-lock registers.
   -Operates with 33-MHz PCI clock and  3.3 V I/O.
Industry-standard packages  (40L TSOP or 32L PLCC) 
Two configurable interfaces
   -Firmware hub interface for platform  operation
   - Address/Address-Multiplexed (A/A Mux) interface for programming during manufacturing
4 or 8 Mbits of flash memory for platform code/data nonvolatile storage
   -Symmetrically blocked, 64-KB memory sections
   - Available in 8-Mbit (Intel®  82802AC) and 4-Mbit (Intel®  82802AB) densities
   - Automated byte program and block erase via an integrated Write State Machine (WSM)
Address/Address-Multiplexed (A/A Mux) interface/mode
   -11-Pin multiplexed address and 8-pin data I/O interface 
   -Supports fast on-board or out-of-system programming for manufacturing
Case temprature operating range
Power supply specifications
   -Vcc: 3.3 V ± 0.3 V
   - Vpp: 3.3 V and 12 V for fast programming, (80 hours maximum) 
 


Pinout

Connection Diagram Connection Diagram
The pin descriptions table details the usage of each device pin. Most pins have dual functionality, with  functions in both the Intel Firmware Hub and A/A Mux interfaces. The A/A Mux functionality for pins is  shown bold italic in the description box for that pin. All pins are designed to be compliant with   VCC + 0.3 V max. unless otherwise noted.


Specifications

Case temperature under bias:.........................-10 to +85
Storage temperature:....................................-65  to +125
Supply voltage with respect to VSS..................-0.2 V to 4.1 V
Voltage On Any Pin (except VPP):-0.5 V to +VCC + 0.5 V(1,2,5) 
VPP voltage:........................................-0.5 V to +14.0 V (1,2,4)
Output short-circuit current:.....................................100 mA(3)

*WARNING: Stressing the device  beyond the ìAbsolute Maximum  Ratingsi may cause permanent  damage. These are stress ratings  only. Operation beyond the  ìOperating Conditionsi is not recommended and extended exposure beyond the ìOperating Conditionsi may affect device reliability.
