MOTOROLA FAST SRAM
MCM63Z818 PIN DESCRIPTIONS
Pin Locations
Symbol
Type
Description
85
ADV
Input
Synchronous Load/Advance: Loads a new address into counter when
low. RAM uses internally generated burst addresses when high.
89
CK
Input
Clock: This signal registers the address, data in, and all control signals
except G and LBO.
87
CKE
Input
Clock Enable: Disables the CK input when CKE is high.
(a) 58, 59, 62, 63, 68, 69, 72, 73, 74
(b) 8, 9, 12, 13, 18, 19, 22, 23, 24
DQx
I/O
Synchronous Data I/O: “x” refers to the byte being read or written
(byte a, b).
86
G
Input
Asynchronous Output Enable.
31
LBO
Input
Linear Burst Order Input: This pin must remain in steady state (this
signal not registered or latched). It must be tied high or low.
Low — linear burst counter.
High — interleaved burst counter.
32, 33, 34, 35, 44, 45, 46,
47, 48, 49, 50, 80, 81, 82, 99, 100
SA
Input
Synchronous Address Inputs: These inputs are registered and must
meet setup and hold times.
37, 36
SA0, SA1
Input
Synchronous Burst Address Inputs: The two LSBs of the address field.
These pins must preset the burst address counter values. These inputs
are registered and must meet setup and hold times.
93, 94
(a) (b)
SBx
Input
Synchronous Byte Write Inputs: Enables write to byte “x”
(byte a, b) in conjunction with SW. Has no effect on read cycles.
98
SE1
Input
Synchronous Chip Enable: Active low to enable chip.
97
SE2
Input
Synchronous Chip Enable: Active high for depth expansion.
92
SE3
Input
Synchronous Chip Enable: Active low for depth expansion.
88
SW
Input
Synchronous Write: This signal writes only those bytes that have been
selected using the byte write SBx pins.
14, 15, 16, 41, 65, 66, 91
VDD
VDDQ
VSS
Supply
Core Power Supply.
4, 11, 20, 27, 54, 61, 70, 77
Supply
I/O Power Supply.
5, 10, 17, 21, 26, 40,
55, 60, 64, 67, 71, 76, 90
Supply
Ground.
1, 2, 3, 6, 7, 25, 28, 29, 30,
38, 39, 42, 43, 51, 52, 53, 56, 57,
75, 78, 79, 83, 84, 95, 96
NC
—
No Connection: There is no connection to the chip.
