SGRAM (Rev. 0.0) Jan'97 Preliminary MITSUBISHI LSIs M5M4V16G50DFP -8, -10, -12 16M (2-BANK x 262144-WORD x 32-BIT) Synchronous Graphics RAM PRELIMINARY Some of contents are described for general products and are subject to change without notice. DESCRIPTION The M5M4V16G50DFP is a 2-bank x 262,144-word x 32-bit Synchronous GRAM, with LVTTL interface. All inputs and outputs are referenced to the rising edge of CLK. The M5M4V16G50DFP can operate at frequencies of 100+ MHz. The BLOCK WRITE and WRITE-PER-BIT functions provide improved performance in graphic memory systems. FEATURES - Single 3.3v±0.3v power supply - Clock frequencies of 125 MHz - Fully synchronous operation referenced to clock rising edge - Dual bank operation controlled by A10(Bank Address) - Internal pipelined operation: column address can be changed every clock cycle - Programmable /CAS Latency (LVTTL: 2 and 3) - Programmable Burst Length (1/2/4/8 and Full Page) - Programmable Burst Type (Sequential / Interleave) - Byte control using DQM0 - DQM3 signals in both read and write cycles - Persistent Write-Per-Bit (WPB) function - 8 Column Block Write (BW) function - Auto Precharge / All bank precharge controlled by A9 - Auto Refresh and Self Refresh Capability - 2048 refresh cycles /32ms - LVTTL Interface - 100 pin QFP package with 0.65mm lead pitch Max.
