All rights reserved. 2Gb: x16, x32 GDDR5 SGRAM Ball Assignments and Descriptions Table 2: 170-Ball FBGA Ball Descriptions Symbol Type Description A[12:0] Input Address inputs: Provide the row address for ACTIVE commands. A[5:0] (A6) provide the column address and A8 defines the auto precharge bit for READ/WRITE commands, to select one location out of the memory array in the respective bank. A8 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one bank (A8 LOW, bank selected by BA[3:0]) or all banks (A8 HIGH). The address inputs also provide the op-code during a MODE REGISTER SET command and the data bits during LDFF commands. A[12:8] are sampled with the rising edge of CK_t and A[7:0] are sampled with the rising edge of CK_c. ABI_n Input Address bus inversion: Reduces the power requirements on address pins by limiting the number of address lines driving LOW to 5. ABI_n is enabled by the corresponding ABI mode register bit. BA[3:0] Input Bank address inputs: Define the bank to which an ACTIVE, READ, WRITE, or PRECHARGE command is being applied. BA[3:0] define which mode register is loaded during the MODE REGISTER SET command. BA[3:0] are sampled with the rising edge of CK_t. CK_t, CK_c Input Clock: CK_t and CK_c are differential clock inputs. Command inputs are latched on the rising edge of CK_t. Address inputs are latched on the rising edge of CK_t and the rising edge of CK_c. All latencies are referenced to CK_t. CK_t and CK_c are externally terminated. WCK01_t, WCK01_c/ WCK23_t, WCK23_c Input Data Clocks: WCK_t and WCK_c are differential clocks used for write data capture and read data output. WCK01_t and WCK01_c are associated with DQ[15:0], DBI0_n, DBI1_n, EDC0, and EDC1. WCK23_t and WCK23_c are associated with DQ[31:16], DBI2_n, DBI3_n, EDC2, and EDC3. WCK clocks operate at nominally twice the CK clock frequency. CKE_n Input Clock enable: CKE_n enables (registered LOW) and disables (registered HIGH) internal circuitry and clocks on the SGRAM. The specific circuitry that is enabled/disabled is dependent upon the device configuration and operating mode. Taking CKE_n HIGH provides PRECHARGE POWER-DOWN and SELF REFRESH operations (all banks idle), or active power-down (row active in any bank). CKE_n is synchronous for power-down entry and exit and for self refresh entry. CKE_n must be maintained LOW throughout read and write accesses. Input buffers (excluding CKE_n) are disabled during SELF REFRESH operation. The value of CKE_n latched at power-up with RESET_n going HIGH determines the termination value of the address and command inputs. CS_n Input Chip select: CS_n enables (registered LOW) and disables (registered HIGH) the command decoder. All commands are masked when CS_n is registered HIGH, but internal command execution continues. CS_n is considered part of the command code. MF Input Mirror function: VDDQ CMOS input. Must be tied to VDDQ or VSS. RAS_n, CAS_n, WE_n Input Command inputs: RAS_n, CAS_n, and WE_n (along with CS_n) define the command being entered. RESET_n Input Reset: RESET_n is an active LOW CMOS input referenced to VSS. A full chip reset may be performed at any time by pulling RESET_n LOW. With RESET_n LOW all ODTs are disabled. SEN Input Scan enable: VDDQ CMOS input. Must be tied to VSS when not in use. PDF: 09005aef858b7e99 2gb_gddr5_sgram_brief.pdf - Rev.

Description DBI[3:0]_n I/O Data bus inversion: Reduces the DC power consumption and supply noise induced jitter on data pins. DBI0_n is associated with DQ[7:0], DBI1_n with DQ[15:8], DBI2_n with DQ[23:16], and DBI3_n with DQ[31:24]. EDC[3:0] Output Error detection code: The calculated CRC data is transmitted on these pins. In addition, these pins drive a hold pattern when idle and can be used as an RDQS function. EDC0 is associated with DQ[7:0], EDC1 with DQ[15:8], EDC2 with DQ[23:16], and EDC3 with DQ[31:24]. VDD Supply Power supply: 1.6V/1.5V ±3% and 1.35V ±3%. VDDQ Supply DQ power supply: 1.6V/1.5V ±3% and 1.35V ±3%. Isolated on the device for improved noise immunity. VREFC Supply Reference voltage for control and address: VREFC must be maintained at all times (including self refresh) for proper device operation. VREFD Supply Reference voltage for data: VREFD must be maintained at all times (including self refresh) for proper device operation. VSS Supply Ground. VSSQ Supply DQ ground: Isolated on the device for improved noise immunity. ZQ Reference NC – PDF: 09005aef858b7e99 2gb_gddr5_sgram_brief.pdf - Rev. A 2/14 EN External reference ball for output drive calibration: This ball is tied to an external 120Ω resistor (ZQ), which is tied to VSSQ. No connect: These balls should be left unconnected (the ball has no connection to the SGRAM or to other balls). 6 Micron Technology, Inc. reserves the right to change products or specifications without notice. © 2014 Micron Technology, Inc.
