S29AL004D70TFIF20H - Brand New SPANSION IC Chips
-
Description
The S29AL004D is a 4 Mbit, 3.0 volt-only Flash memory organized as 524,288 bytes or 262,144 words. The device is offered in 48-ball FBGA, 44-pin SO, and 48-pin TSOP packages. The word-wide data (x16) appears on DQ15–DQ0; the byte-wide (x8) data appears on DQ7–DQ0. This device requires only a single, 3.0 volt VCC supply to perform read, program, and erase operations. A standard EPROM programmer can also be used to program and erase the device.
Specifications and features
Architectural Advantages:
- Single power supply operation (2.7 to 3.6 volt read and write operations for battery powered applications)
- Manufactured on 200nm process technology (compatible with 320nm Am29LV400B and MBM29LV400T/BC)
- Flexible sector architecture: one 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and seven 64 Kbyte sectors (byte mode); one 8 Kword, two 4 Kword, one 16 Kword, and seven 32 Kword sectors (word mode); supports full chip erase
- Unlock Bypass Program Command: reduces overall programming time when issuing multiple program command sequences
- Top or bottom boot block configurations available
- Embedded Algorithms: embedded Erase algorithm automatically preprograms and erases the entire chip or any combination of designated sectors; embedded Program algorithm automatically writes and verifies data at specified addresses
- Compatibility with JEDEC standards: pinout and software compatible with single-power supply Flash; superior inadvertent write protection
- Sector Protection features: hardware method of locking a sector to prevent any program or erase operations within that sector; sectors can be locked in-system or via programming equipment; temporary Sector Unprotect feature allows code changes in previously locked sectorsPerformance Characteristics:
- High performance: access times as fast as 70 ns
- Ultra low power consumption (typical values at 5 MHz): 200 nA Automatic Sleep mode current, 200 nA standby mode current, 9 mA read current, 20 mA program/erase current
- Cycling Endurance: 1,000,000 cycles per sector typical
- Data Retention: 20 years typicalApplication Scenarios
Data# Polling and toggle bits: provides a software method of detecting program or erase operation completion
Erase Suspend/Erase Resume: suspends an erase operation to read data from, or program data to, a sector that is not being erased, then resumes the erase operationComparison
Advantages- Single power supply operation for battery powered applications
