Features
Functional Description
■ Supports 133-MHz bus operations
■ 1M × 36/2M × 18 common I/O
■ 3.3 V core power supply
The CY7C1441KV33/CY7C1443KV33/CY7C1441KVE33 are
3.3 V, 1M × 36/2M × 18/1M × 36 synchronous flow-through
SRAMs, respectively designed to interface with high-speed
microprocessors with minimum glue logic. Maximum access
delay from clock rise is 6.5 ns (133 MHz version). A 2-bit on-chip
counter captures the first address in a burst and increments the
address automatically for the rest of the burst access. All
synchronous inputs are gated by registers controlled by a
positive-edge-triggered Clock (CLK) input. The synchronous
inputs include all addresses, all data inputs, address-pipelining
Chip Enable (CE1), depth-expansion Chip Enables (CE2 and
CE3), Burst Control inputs (ADSC, ADSP, and ADV), Write
Enables (BWx, and BWE), and Global Write (GW).
Asynchronous inputs include the Output Enable (OE) and the ZZ
pin.
■ 2.5 V or 3.3 V I/O power supply
■ Fast clock-to-output times
❐ 6.5 ns (133 MHz version)
■ Provide high-performance 2-1-1-1 access rate
■ User-selectable burst counter supporting Intel Pentium
interleaved or linear burst sequences
■ Separate processor and controller address strobes
■ Synchronous self-timed write
■ Asynchronous output enable
CY7C1441KVE33
The CY7C1441KV33/CY7C1443KV33/
allow
either interleaved or linear burst sequences, selected by the
MODE input pin. A HIGH selects an interleaved burst sequence,
while a LOW selects a linear burst sequence. Burst accesses
can be initiated with the Processor Address Strobe (ADSP) or the
cache Controller Address Strobe (ADSC) inputs. Address
advancement is controlled by the Address Advancement (ADV)
input.
■ CY7C1441KV33, CY7C1443KV33, and CY7C1441KVE33 are
available in JEDEC-standard 100-pin TQFP and 165-ball
FBGA Pb-free packages.
■ IEEE 1149.1 JTAG-Compatible Boundary Scan
■ “ZZ” Sleep Mode option
■ On-chip error correction code (ECC) to reduce soft error rate
(SER)
Addresses and chip enables are registered at rising edge of
clock when either Address Strobe Processor (ADSP) or Address
Strobe Controller (ADSC) are active. Subsequent burst
addresses can be internally generated as controlled by the
Advance pin (ADV).
The
CY7C1441KV33/CY7C1443KV33/CY7C1441KVE33
operate from a +3.3 V core power supply while all outputs may
operate with either a +2.5 V or +3.3 V supply. All inputs and
outputs are JEDEC-standard JESD8-5-compatible.
