据《EDN》1986年31卷5期报道:低功率CMOS EPROM系列,除了VT27C256256kb的EPROM外,现又出现T64kb(VT27C64)、128kb(VT27-C128)和512kb(VT27-C512)型号。这种EPROM使用12V程序电压,并提供150到25C毫微秒的访问时间。该器件通过微片给输入赋能,可自动降低电源损耗。另外,这种器件还具有消除总线争用矛盾的输出赋能功能。与TTL兼容的EPROM是一种有28条腿的陶瓷双列直插式组件。64kb、128kb和512kb器件均由VLSI技术公司生产,它们的售价分别为4.50、7.81和15.28美元。
According to “EDN” 1986 Vol. 31, No. 5: Low power CMOS EPROM series, in addition to the VT27C256256kb EPROM, are now appeared T64kb (VT27C64), 128kb (VT27-C128) and 512kb (VT27-C512) models. This EPROM uses 12V program voltage and provides 150 to 25C nanosecond access time. The device energizes input through the microchip to automatically reduce power loss. In addition, this device also has to eliminate the conflict of bus contention output enable function. The TTL-compatible EPROM is a 28-legged ceramic dual in-line package. The 64kb, 128kb and 512kb devices are manufactured by VLSI Technologies and are selling for 4.50, 7.81 and 15.28 dollars respectively.
