16-Mbit (1M Words × 16 Bit) Static RAM
with Error-Correcting Code (ECC)
16-Mbit (1 M words × 16 bit) Static RAM with Error-Correcting Code (ECC)
Features
Data writes are performed by asserting the Write Enable input
(WE) LOW, and providing the data and address on device data
(I/O0 through I/O15) and address (A0 through A19) pins
respectively. The Byte High/Low Enable (BHE, BLE) inputs
control byte writes, and write data on the corresponding I/O lines

Temperature Ranges:
❐ Automotive-A: -40 C to +85 C
❐ Automotive-E: -40 C to +125 C

■
Available in Pb-free 48-ball VFBGA and 48-pin TSOP I
packages
to the memory location specified. BHE controls I/O8 through
I/O15; BLE controls I/O0 through I/O7.
Data reads are performed by asserting the Output Enable (OE)
input and providing the required address on the address lines.
Read data is accessible on I/O lines (I/O0 through I/O15). Byte
accesses can be performed by asserting the required byte
enable signal (BHE, BLE) to read either the upper byte or the
lower byte of data from the specified address location.
All I/Os (I/O0 through I/O15) are placed in a HI-Z state when the
device is deselected (CE1 HIGH / CE2 LOW for dual chip-enable
device), or control signals are de-asserted (OE, BLE, and BHE).
Functional Description
CY62167G is high-performance CMOS low-power (MoBL)
SRAM devices with embedded ECC. This device is offered in
dual chip-enable.
Devices with dual chip-enable are accessed by asserting both
chip-enable inputs – CE1 as LOW and CE2 as HIGH.
These devices also have a unique “Byte Power down” feature
where if both the Byte Enables (BHE and BLE) are disabled, the
devices seamlessly switches to standby mode irrespective of the
state of the chip enable(s), thereby saving power.
The CY62167G device is available in a Pb-free 48-ball VFBGA
and 48-pin TSOP I packages. The device in the 48-pin TSOP I
package can also be configured to function as a 2 M words × 8
bit device.The logic block diagram is on page 2. Refer to Pin
Configurations on page 4 and the associated footnotes for
details.
Note
1. This device does not support automatic write-back on error detection.

Notes
2. NC pins are not connected internally to the die and are typically used for address expansion to a higher-density device. Refer to the respective datasheets for pin
configuration.
3. The BYTE pin in the 48-pin TSOP I package must be tied to VCC to use the device as a 1 M × 16 SRAM. The 48-pin TSOP I package can also be used as a 2 M × 8
SRAM by tying the BYTE signal to VSS. In the 2 M × 8 configuration, pin 45 is A20, while BHE, BLE and I/O8 to I/O14 pins are not used.

Notes
14. Test conditions assume signal transition time (rise/fall) of 3 ns or less, timing reference levels of 1.5 V (for VCC > 3 V) and VCC/2 (for VCC < 3 V), and input pulse levels
of 0 to 3 V (for VCC > 3 V) and 0 to VCC (for VCC < 3 V). Test conditions for the read cycle use output loading shown in AC Test Loads and Waveforms section, unless specified
otherwise.
15. At any temperature and voltage condition, tHZCE is less than tLZCE, tHZBE is less than tLZBE, tHZOE is less than tLZOE, and tHZWE is less than tLZWE for any device.
16. tHZOE, tHZCE, tHZBE, and tHZWE transitions are measured when the outputs enter a high impedance state.
17. The internal write time of the memory is defined by the overlap of WE = VIL, CE1 = VIL, BHE or BLE or both = VIL, and CE2 = VIH. All signals must be ACTIVE to initiate
a write. Any of these signals can terminate a write by going INACTIVE. The data input setup and hold timing must refer to the edge of the signal that terminates the write.
