GENERAL DESCRIPTION
The S70GL256M00 consists of two 128 Mbit, 3.0 volt single power supply flash memory devices and is organized as 8,388,608 doublewords or 16,777,216 words. The device has a 32-bit wide data bus that can also function as an 16-bit wide data bus by using the WORD# input. The device can be programmed either in the host system or in standard EPROM programmers.

Distinctive Characteristics
ARCHITECTURAL ADVANTAGES
■ Single power supply operation
   — 3 volt read, erase, and program operations
■ VersatileI/OTM control
   — Device generates data output voltages and tolerates
      data input voltages on the CE# and DQ inputs/outputs
      as determined by the voltage on the VIO pin; operates
      from 1.65 to 3.6 V
■ Manufactured on 0.23 µm MirrorBitTM process technology
■ SecSi™ (Secured Silicon) Sector region
   — 128-doubleword/256-word sector for permanent,
      secure identification through an
      8-doubleword/16-word random Electronic Serial
      Number, accessible through a command sequence
   — May be programmed and locked at the factory or by
      the customer
■ Flexible sector architecture
   — Two hundred fifty-six 32 Kdoubleword (64 Kword) sectors
■ Compatibility with JEDEC standards
   — Provides pinout and software compatibility for
      single-power supply flash, and superior inadvertent
      write protection
■ 100,000 erase cycles typical per sector
■ 20-year data retention typical

PERFORMANCE CHARACTERISTICS
■ High performance
   — 110 ns access time
   — 30 ns page read times
   — 0.5 s typical sector erase time
   — 15 µs typical write buffer doubleword programming
      time: 16-doubleword/32-word write buffer reduces
      overall programming time for multiple-word updates
   — 4-doubleword/8-word page read buffer
   — 16-doubleword/32-word write buffer
■ Low power consumption (typical values at 3.0 V, 5 MHz)
   — 26 mA typical active read current
   — 100 mA typical erase/program current
   — 2 µA typical standby mode current
■ Package options
   — 80-ball Fortified BGA

SOFTWARE & HARDWARE FEATURES
■ Software features
   — Program Suspend & Resume: read other sectors
      before programming operation is completed
   — Erase Suspend & Resume: read/program other
      sectors before an erase operation is completed
   — Data# polling & toggle bits provide status
   — Unlock Bypass Program command reduces overall
      programming time
   — CFI (Common Flash Interface) compliant: allows host
      system to identify and accommodate multiple flash
      devices
■ Hardware features
   — Sector Group Protection: hardware-level method of
      preventing write operations within a sector group
   — Temporary Sector Group Unprotect: VID-level method
      of changing code in locked sector groups
   — WP#/ACC input accelerates programming time
      (when high voltage is applied) for greater throughput
      during system production. Protects first or last sector
      group regardless of sector group protection settings
   — Hardware reset input (RESET#) resets device
   — Ready/Busy# output (RY/BY#) detects program or
      erase cycle completion
