Static Random Access Parallel NOR Flash Embedded Memory Chip
MT28EW256ABA1HPC-0SIT
Features
• Single-level cell (SLC) process technology
• Density: 256Mb
• Supply voltage– VCC = 2.7–3.6V (program, erase, read)– VCCQ =
1.65 - VCC (I/O buffers)
• Asynchronous random/page read– Page size: 16 words or 32 bytes–
Page access: 20ns– Random access: 70ns (VCC = VCCQ = 2.7-3.6V)–
Random access: 75ns (VCCQ = 1.65-VCC)
• Buffer program (512-word program buffer)– 2.0 MB/s (TYP) when
using full buffer program– 2.5 MB/s (TYP) when using accelerated
buffer
program (VHH)
• Word/Byte program: 25us per word (TYP)
• Block erase (128KB): 0.2s (TYP)
• Memory organization– Uniform blocks: 128KB or 64KW each– x8/x16
data bus
• Program/erase suspend and resume capability– Read from another
block during a PROGRAM
SUSPEND operation– Read or program another block during an ERASE
SUSPEND operation
• Unlock bypass, block erase, chip erase, and write to
buffer capability
• BLANK CHECK operation to verify an erased block
• CYCLIC REDUNDANCY CHECK (CRC) operation to
verify a program pattern
• VPP/WP# protection– Protects first or last block regardless of
block
protection settings
• Software protection– Volatile protection– Nonvolatile protection–
Password protection
• Extended memory block– 128-word (256-byte) block for permanent,
secure
identification– Programmed or locked at the factory or by the
customer
• JESD47-compliant– 100,000 (minimum) ERASE cycles per block– Data
retention: 20 years (TYP)
• Package– 56-pin TSOP, 14 x 20mm (JS)– 64-ball LBGA, 11 x 13mm
(PC)– 56-ball VFBGA, 7 x 9mm (PN)
• RoHS-compliant, halogen-free packaging
• Operating temperature– Ambient: –40°C to +85°C
