| 27C1512T 512Kb (32K x 16-bit) OTP EPROM MCM Memory Logic Diagram FEATURES: * 32K x 16 Bit OTP EPROM organization * RAD-PAK(R) radiation-hardened against natural space radiation * Total dose hardness: - > 100 Krad (Si), depending upon space mission * Excellent Single Event Effects: - SELTH LET: > 80 MeV/mg/cm2 - SEUTH LET: > 80 Mev/mg/cm2 * Package: - 40 pin RAD-PAK(R) DIP * Low power consumption: - Active mode: 500 mW @ 10 MHz - Standby mode: < 11 mW * High speed page and word programming: - Page programming time: 14 sec (typ) * Programming power supply: - VPP = 12.5 V 0.3 V * One-time Programmable * Pin Arrangement - Flash memory and mask ROM compatible DESCRIPTION: Maxwell Technologies' 27C1512T high density 512K OneTime Programmable Electrically Programmable Read Only Memory multi-chip module (MCM) features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. The 27C1512T features fast address times and low power dissipation. The 27C1512T offers high speed programming using page programming mode. Maxwell Technologies' patented RAD-PAK(R) packaging technology incorporates radiation shielding in the microcircuit package. It eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission. In a GEO orbit, RAD-PAK(R) provides greater than 100 krad (Si) radiation dose tolerance.
