DESCRIPTION
The DS2223 and DS2224 EconoRAMs are fully static, micro–powered, read/write memories in low–cost TO–92 or SOT–223 packages. The DS2223 is organized as a serial 256 x 1 bit static read/write memory. The DS2224’s first 32 bits are lasered with a unique ID code at the time of manufacture; the remaining 224 bits are static read/write memory. Signaling necessary for reading or writing is reduced to just one interface lead.
FEATURES
• Low–cost, general–purpose, 256–bit memory
– DS2223 has 256–bit SRAM
– DS2224 has 32–bit ROM, 224–bit SRAM
• Reduces control, address and data interface to a single pin
• Each DS2224 32–bit ROM is factory–lasered with a unique serial number
• DS2224 portion of ROM with custom code and unique serial number available
• Minimal operating power: 45 nanocoulombs per transaction @1.5V typical
• Less than 15 nA standby current at 25°C
• Nonvolatile data retention easily achieved via low–cost alkaline batteries or capacitors
• Directly connects to a port pin of popular microcontrollers
• Operation from 1.2 to 5.5 volts
• Popular TO–92 or SOT–223 surface mount package
• Operates over industrial temperature range –40°C to +85°C
