1 / 42 page  FINAL Publication# 18723 Rev: C Amendment/+1 Issue Date: May 1998 AmC0XXCFLKA 1, 2, 4, or 10 Megabyte 5.0 V-only Flash Memory PC Card DISTINCTIVE CHARACTERISTICS s High performance — 150 ns maximum access time s Single supply operation — Write and erase voltage, 5.0 V ±5% — Read voltage, 5.0 V ±5% s CMOS low power consumption — 45 mA maximum active read current (x8 mode) — 65 mA maximum active erase/write current (x8 mode) s High write endurance — Minimum 100,000 erase/write cycles s PCMCIA/JEIDA 68-pin standard — Selectable byte- or word-wide configuration s Write protect switch — Prevents accidental data loss s Zero data retention power — Batteries not required for data storage s Separate attribute memory — 512 byte EEPROM s Automated write and erase operations increase system write performance — 64K byte memory sectors for faster automated erase speed — Typically 1.5 seconds per single memory sector erase — Random address writes to previously erased bytes (16 µs typical per byte) s Total system integration solution — Support from independent software and hardware vendors s Low insertion and removal force — State-of-the-art connector allows for minimum card insertion and removal effort s Sector erase suspend/resume — Suspend the erase operation to allow a read operation in another sector within the same device GENERAL DESCRIPTION AMD’s 5.0 V-only Flash Memory PC Card provides the highest system level performance for data and file stor- age solutions to the portable PC market segment. Man- ufactured with AMD’s Negative Gate Erase, 5.0 V-only technology, the AMD 5.0 V-only Flash Memory Cards are the most cost-effective and reliable approach to single-supply Flash memory cards. Data files and ap- plication programs can be stored on the “C” series cards. This allows OEM manufacturers of portable sys- tems to eliminate the weight, high power consumption and reliability issues associated with electromechanical disk-based systems. The “C” series cards also allow to- day’s bulky and heavy battery packs to be reduced in weight and size. Typically only two “AA” alkaline batter- ies are required for total system operation. AMD’s Flash Memory PC Cards provide the most efficient method to transfer useful work between different hard- ware platforms. The enabling technology of the “C” se- ries cards enhances the productivity of mobile workers. Widespread acceptance of the “C” series cards is as- sured due to their compatibility with the 68-pin PCM- CIA/JEIDA international standard. AMD’s Flash Memory Cards can be read in either a byte-wide or word-wide mode which allows for flexible integration into various system platforms. Compatibility is assured at the hardware interface and software interchange specification. The Card Information Structure (CIS) or Metaformat, can be written by the OEM at the memory card’s attribute memory address space beginning at address 00000H by using a format utility. The CIS ap- pears at the beginning of the Card’s attribute memory space and defines the low-level organization of data on the PC Card. The “C” series cards contains a separate 512 byte EEPROM memory for the cards’ attribute memory space. This allows all of the Flash memory to be used for the common memory space. Third party software solutions such as Microsoft’s Flash File System (FFS), M-System’s True FFS, and SCM’s SCM-FFS, enable AMD’s Flash Memory PC Card to replicate the function of traditional disk-based memory systems. |
