Automotive Mobile LPDDR2 SDRAM
MT42L32M16D1, MT42L32M32D2, MT42L16M32D1
Features
• Ultra low-voltage core and I/O power supplies – VDD2 = 1.14–1.30V – VDDCA/VDDQ = 1.14–1.30V – VDD1 = 1.70–1.95V
• Clock frequency range – 400–10 MHz (data rate range: 800–20 Mb/s/pin)
• Four-bit prefetch DDR architecture • Four internal banks for concurrent operation • Multiplexed, double data rate, command/address
inputs; commands entered on every CK edge • Bidirectional/differential data strobe per byte of
data (DQS/DQS#) • Programmable READ and WRITE latencies (RL/WL) • Programmable burst lengths: 4, 8, or 16 • On-chip temperature sensor to control self refresh
rate • Partial-array self refresh (PASR) • Deep power-down mode (DPD) • Selectable output drive strength (DS) • Clock stop capability • RoHS-compliant, “green” packaging
Options
• VDD2: 1.2V • Configuration
– 4 Meg x 32 x 4 banks – 8 Meg x.
