W55412A - VOICE PROM

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.
