CY7C026A-20AXCT MCU Code Reading

CY7C026A-20AXCT MCU Code Reading, Programm Reading, MCU Crack, Chip Decryption.

The CY7C026A is a low power CMOS 16K x 16 dual-port static
RAM. Various arbitration schemes are included on the devices
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 device can be utilized as standalone 16-bit
dual-port static RAM or multiple devices can be combined to
function as a 32-bit or wider master/slave dual-port static RAM.
An M/S pin is provided for implementing 32-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 the chip enable pin.
The CY7C026A is available in 100-pin thin quad plastic flatpack
(TQFP) packages.
