W19B320AT/B
1. GENERAL DESCRIPTION
The W19B320AT/B is a 32Mbit, 2.7~3.6-volt flexible bank CMOS flash memory organized as 4M x 8
or 2M × 16 bits. The word-wide ( × 16) data appears on DQ15-DQ0, and byte-wide (x 8) data appears
on DQ7-DQ0. The device can be programmed and erased in-system with a standard 3.0-volt power
supply. A 12-volt V PP is not required. The unique cell architecture of the W19B320AT/B results in fast
program/erase operations with extremely low current consumption (compared to other comparable
3-volt flash memory products). The device can also be programmed and erased by using standard
EPROM programmers.
2. FEATURES
Performance
? 2.7~3.6-volt write (program and erase)
operations
? Fast write operation
? Sector erases time: 0.4 Sec (typical)
? Chip erases time: 49 Sec (typical)
? Byte programming time: 5 μ s (typical)
? Read access time: 70 ns
? Typical program/erase cycles:
? 100K
? Twenty-year data retention
? Ultra low power consumption
? Active current (Read): 10 mA (typical)
? Active current (Read while Erase/Program):
21 mA (typical)
? Standby current: 0.2 μ A (typical)
Architecture
? Flexible Bank architectures
? Consist of four banks that customer can
group the bank size as they needed
? Bank 1: 4M; Bank 2: 12M;
Bank 3: 12M; Bank 4: 4M
? Security Sector Size: 256 Bytes
? The Security Sector is an OTP; once the
sector is programmed, it cannot be erased
? Simultaneous Read/write operation
? Data can be continuously read from one bank
? JEDEC standard byte-wide and word-wide
pinouts
? Manufactured on WinStack 0.18 μ m process
technology
? Available packages: 48-pin TSOP and 48-ball
TFBGA (6x8mm)
Software Features
? Compatible with common Flash Memory
Interface (CFI) specification
? Flash device parameters stored directly on
the device
? Allows software driver to identify and use a
variety of different current and future Flash
products
? Erase Suspend/Erase Resume
? Suspends erase operations to allow
programming in same bank
? End of program detection
? Software method: Toggle bit/Data polling
? Unlock Bypass Program command
? Reduces overall programming time when
issuing multiple program command
sequences
Hardware Features
? Ready/#Busy output (RY/#BY)
? Detect program or erase cycle completion
? Hardware reset pin (#RESET)
? Reset the internal state machine to the read
mode
while processing erase/program functions in
other bank with zero latency
