FEATURES:

  • 32K x 16 Bit OTP EPROM organization R AD-PAK® radiation-hardened against natural space radia- tion  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® 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: - V PP = 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 dissipa- tion. The 27C1512T offers high speed programming using page programming mode. Maxwell Technologies' patented R AD-PAK® packaging technol- ogy incorporates radiation shielding in the microcircuit pack- age. 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, R AD-PAK® provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Maxwell Technologies self-defined Class Logic Diagram
