Features 15 0 20 The Byte High Enable (BHE) and Byte Low Enable (BLE) inputs Ultra-low standby current control byte writes and write data on the corresponding I/O lines Typical standby current: 3 A to the memory location specified. BHE controls I/O through 8 Maximum standby current: 19 A I/O and BLE controls I/O through I/O . 15 0 7 High speed: 55 ns To perform data reads, assert the Output Enable (OE) input and provide the required address on the address lines. You can Embedded error-correcting code (ECC) for single-bit error 1 access read data on the I/O lines (I/O through I/O ). To perform 0 15 correction byte accesses, assert the required byte enable signal (BHE or Operating voltage range: 2.2 V to 3.6 V BLE) to read either the upper byte or the lower byte of data from the specified address location. 1.5-V data retention All I/Os (I/O through I/O ) are placed in a high-impedance state 0 15 Transistor-transistor logic (TTL) compatible inputs and outputs when the device is deselected (CE HIGH for a single chip enable Error indication (ERR) pin to indicate 1-bit error detection and device and CE HIGH / CE LOW for a dual chip enable device), 1 2 correction or the control signals are de-asserted (OE, BLE, BHE). 48-pin TSOP I package configurable as 2M 16 or 4M 8 These devices have a unique Byte Power-down feature where, SRAM if both the Byte Enables (BHE and BLE) are disabled, the devices seamlessly switch to the standby mode irrespective of Available in Pb-free 48-ball VFBGA and 48-pin TSOP I the state of the chip enables, thereby saving power. packages On the CY62177GE30 devices, the detection and correction of Functional Description a single-bit error in the accessed location is indicated by the assertion of the ERR output (ERR = High). See the Truth Table CY62177G30 and CY62177GE30 are high-performance CMOS, 2 CY62177G30/CY62177GE30 on page 15 for a complete low-power (MoBL ) SRAM devices with embedded ECC . Both description of read and write modes. devices are offered in single and dual chip enable options and in multiple pin configurations. The CY62177GE30 device includes The CY62177G30 and CY62177GE30 devices are available in an ERR pin that signals a single-bit error-detection and a Pb-free 48-pin TSOP I package and 48-ball VFBGA packages. correction event during a read cycle. The logic block diagrams are on page 2. To access devices with a single chip enable input, assert the chip The device in the 48-pin TSOP I package can also be configured enable (CE) input LOW. To access dual chip enable devices, to function as a 4M words 8 bit device. Refer to the Pin assert both chip enable inputs CE as LOW and CE as HIGH.
