S27KL0642GABHV020集成电路（IC）的存储器规格书PDF中文资料

特性 Features

• Interface

- HYPERBUS™ interface

- 1.8 V / 3.0 V interface support

• Single-ended clock (CK) - 11 bus signals

• Optional differential clock (CK, CK#) - 12 bus signals

- Chip select (CS#)

- 8-bit data bus (DQ[7:0])

- Hardware reset (RESET#)

- Bidirectional read-write data strobe (RWDS)

• Output at the start of all transactions to indicate refresh latency

• Output during read transactions as Read data strobe

• Input during write transactions as Write data mask

- Optional DDR center-aligned read strobe (DCARS)

• During read transactions RWDS is offset by a second clock, phase shifted from CK

• The phase shifted clock is used to move the RWDS transition edge within the read data eye

• Performance, power, and packages

- 200 MHz maximum clock rate

- DDR - transfers data on both edges of the clock

- Data throughput up to 400 MBps (3,200 Mbps)

- Configurable burst characteristics:

• Linear burst

- Wrapped burst lengths:

• 16 bytes (8 clocks)

• 32 bytes (16 clocks)

• 64 bytes (32 clocks)

• 128 bytes (64 clocks)

- Hybrid option - one wrapped burst followed by linear burst

• Configurable output drive strength

• Power modes

- Hybrid Sleep mode

- Deep power-down

• Array refresh

- Partial memory array (1/8, 1/4, 1/2, and so on)

- Full

• Package
