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 VPP 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  
JEDEC standard byte-wide and word-wide  
pinouts  
2.7~3.6-volt write (program and erase)  
operations  
Manufactured on WinStack 0.18μm process  
technology  
Fast write operation  
Available packages: 48-pin TSOP and 48-ball  
TFBGA (6x8mm)  
Sector erases time: 0.4 Sec (typical)  
Chip erases time: 49 Sec (typical)  
Byte programming time: 5 μs (typical)  
Software Features  
Compatible with common Flash Memory  
Interface (CFI) specification  
Read access time: 70 ns  
Typical program/erase cycles:  
100K  
Flash device parameters stored directly on  
the device  
Allows software driver to identify and use a  
variety of different current and future Flash  
products  
Twenty-year data retention  
Ultra low power consumption  
Erase Suspend/Erase Resume  
Suspends erase operations to allow  
programming in same bank  
Active current (Read): 10 mA (typical)  
Active current (Read while Erase/Program):  
21 mA (typical)  
End of program detection  
Standby current: 0.2 μA (typical)  
Architecture  
Software method: Toggle bit/Data polling  
Unlock Bypass Program command  
Flexible Bank architectures  
Reduces overall programming time when  
issuing multiple program command  
sequences  
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  
Hardware Features  
Ready/#Busy output (RY/#BY)  
Detect program or erase cycle completion  
Hardware reset pin (#RESET)  
Security Sector Size: 256 Bytes  
The Security Sector is an OTP; once the  
sector is programmed, it cannot be erased  
Simultaneous Read/write operation  
Reset the internal state machine to the read  
mode  
Data can be continuously read from one bank  
while processing erase/program functions in  
other bank with zero latency
