CY8C201A0-LDX2I Operating Modes of I2C Commands
Normal Mode
In normal mode of operation, the acknowledgment time is
optimized. The timings remain approximately the same for
different configurations of the slave. To reduce the
acknowledgment times in normal mode, the registers
0x06–0x09, 0x0C, 0x0D, 0x10–0x17, 0x50, 0x51, 0x57–0x60,
0x7E are given only read access. Write to these registers can be
done only in setup mode.
Setup Mode
All registers have read and write access (except those which are
read only) in this mode. The acknowledgment times are longer
compared to normal mode. When CapSense scanning is
disabled (command code 0x0A in command register 0xA0), the
acknowledgment times can be improved to values similar to the
normal mode of operation.

The CY7C024E/CY7C0241E and CY7C025E/CY7C0251E are
low-power CMOS 4K × 16/18 and 8K × 16/18 dual-port static
RAMs. Various arbitration schemes are included on the
CY7C024E/CY7C0241E and CY7C025E/CY7C0251E to handle
situations when multiple processors access the same piece of
data. Two ports are provided, permitting independent,
asynchronous access for reads and writes to any location in
memory. The CY7C024E/CY7C0241E and
CY7C025E/CY7C0251E can be used as standalone 16 or 18-bit
dual-port static RAMs or multiple devices can be combined to
function as a 32-/36-bit or wider master/ slave dual-port static
RAM. An M/S pin is provided for implementing 32-/36-bit or wider
memory applications without the need for separate master and
slave devices or additional discrete logic. Application areas
include interprocessor/multiprocessor designs, communications
status buffering, and dual-port video/graphics memory.
Each port has independent control pins: Chip Enable (CE), Read
or Write Enable (R/W), and Output Enable (OE). Two flags are
provided on each port (BUSY and INT). BUSY signals that the
port is trying to access the same location currently being
accessed by the other port. The Interrupt Flag (INT) permits
communication between ports or systems by means of a mail
box. The semaphores are used to pass a flag, or token, from one
port to the other to indicate that a shared resource is in use. The
semaphore logic is comprised of eight shared latches. Only one
side can control the latch (semaphore) at any time. Control of a
semaphore indicates that a shared resource is in use. An
automatic power-down feature is controlled independently on
each port by a CE pin.
The CY7C024E/CY7C0241E and CY7C025E/CY7C0251E are
available in 100-pin Pb-free TQFP.
