W55412A  
VOICE PROM (256K OTP)  
GENERAL DESCRIPTION  
The W55412A is a 256K ´ 1 bit one-time programmable (OTP) ROM. The W55412A is designed for  
easy cascading with Winbond speech ICs to emulate sounds and functions. The W55412A data ROM  
allows synthesis of messages of up to 12 seconds in duration (not including repetition or silence).  
FEATURES  
· Provides RDP, WRP, and DATA pins to cascade with Winbond speech ICs  
· Data and address are processed in serial form  
· Suitable for low pin count applications (8-pin DIP)  
· Low power consumption:  
- Operating: 3 mA (max.)  
- Standby: 1mA (max.)  
· Programming voltage (VPP): 12 to 12.5V  
· Operating voltage range: 3 to 5V  
· Organized as 256K ´ 1 bit  
· Data access time: 500 nS (max.)
