MSM27C401CZ
524,288-Word x 8-Bit One Time PROM
DESCRIPTION
The MSM27C401CZ is a 4Mbit electrically Programmable Read-Only Memory organized as 524,288
word x 8bit. The MSM27C401CZ operates on a single +3V-5V power supply and is TTL compatible. Since the MSM27C401CZ operates asynchronously , external clocks are not required , making this device easy-to-use. The MSM27C401CZ is suitable as large-capacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 32-pin DIP, 32-pin SOP or 32-pin TSOP packages.
FEATURES
• Single +3V-5V power supply
• Access time 150ns access time (Vcc=+3V) 120ns access time (Vcc=+3.3V) 80ns access time (Vcc=+5V)
• Input / Output TTL compatible
• Three-state output
• Packages 32-pin plastic DIP (DIP32-P-600-2.54) 32-pin plastic SOP (SOP32-P-525-1.27-K) 32-pin plastic TSOP (TSOP I 32-P-814-0.50-K)
