1 / 12 page ¡ Semiconductor MSM6389C 1/11 GENERAL DESCRIPTION The MSM6389C is a solid-state recorder data register in 1,048,576 words x 1 bit configuration. The MSM6389C has a built-in internal address generator circuit allowing continuous serial read/ write operation by single external clock input. The internal address is automatically incremented by one by read/write operation. Address designation in units of 1024 words in the direction of words is possible by an external serial address input. The built-in refresh timer and refresh counter have eliminated the need of an external refresh circuit and realized a low power consumption. 18-pin plastic QFJ is used as the package and the operating temperature range is between 0 °C and 70 °C. The MSM6389C is suitable for storing large capacity data with battery backup. A solid state recording and playback system can easily be constructed in combination with OKI’s voice synthesizer ICs. FEATURES • Configuration: 1,048,576 x 1 bit • Serial access operation: Serial access time 1.5 ms (3.0 ms) Serial read/write cycle time 2.0 ms (4.0 ms) Fast mode read/write cycle time 0.4 ms (0.4 ms) Times in parentheses indicate ones in self-refresh mode. • Low current consumption: 100 mA max. (for data holding, VCC=4.0V) • Wide operating supply voltage range: Single 3.5 to 5.5V • Auto-refresh/self-refresh changeable • Package: 18-pin plastic QFJ (QFJ18-P-R290-1.27) (Product name: MSM6389CJS) ¡ Semiconductor MSM6389C 1,048,576-Word x 1-Bit Solid-State Recorder Data Register E2D0033-39-21 This version: Feb. 1999 Previous version: May. 1997 |
