We are Using CY62157V . we need Configruation setting for LPC4088 Controller.we are using folliwing configruation setting which corruts data in SRAM.:

typedef struct {

uint8_t ChipSelect; /*!< Chip select */

uint32_t Config; /*!< Configuration value */

int32_t WaitWen; /*!< Write Enable Wait */

int32_t WaitOen; /*!< Output Enable Wait */

int32_t WaitRd; /*!< Read Wait */

int32_t WaitPage; /*!< Page Access Wait */

int32_t WaitWr; /*!< Write Wait */

int32_t WaitTurn; /*!< Turn around wait */

} IP_EMC_STATIC_CONFIG_T;

STATIC const IP_EMC_STATIC_CONFIG_T CY62157EV30_config = {

1,

EMC_STATIC_CONFIG_MEM_WIDTH_16 |

EMC_STATIC_CONFIG_CS_POL_ACTIVE_LOW |

EMC_STATIC_CONFIG_BLS_HIGH /* |

EMC_CONFIG_BUFFER_ENABLE*/,

EMC_NANOSECOND(0),

EMC_NANOSECOND(35),

EMC_NANOSECOND(70),

EMC_NANOSECOND(70),

EMC_NANOSECOND(45),

EMC_CLOCK(4)

};

please send perfect Configuation setting.

Hi Chaitanya Kulkarni,

Timing information for write and read operation of our part CY62157EV is available in our datasheet. Please refer "Switching Characteristics" on page 7 of our datasheet, http://www.cypress.com/file/43801/download . Please let us know if you need any clarification about any of the datasheet parameters.

Thanks and Regards,

Sudheesh

Hi Chaitanya Kulkarni,

We are not familiar with controller LPC4088. As the manufacturer of this controller is NXP, we request you to contact NXP for support. You can get back to us if you need any clarification about any of the datasheet specs of our device CY62157EV.

Thanks and Regards,

Hello Sudheesh,

I know you are not familiar with this controller,but can you send us

application code of Your SRAM with any Controller. Actually we have code

for Static RAM But we Don't Have Configuration values(Timings). So we Need

Any Application Code.through that we can Set Configuration Values.
