D CAT1320, CAT1321 DEVICE OPERATION Reset Controller Description The CAT1320/21 precision Reset controllers ensure correct system operation during brownout and power up/down conditions. They are configured with opendrain RESET/RESET outputs. During power-up, the RESET/RESET output remains active until VCC reaches the VTH threshold and will continue driving the outputs for approximately 200ms (tPURST) after reaching VTH. After the tPURST timeout interval, the device will cease to drive the reset output. At this point the reset output will be pulled up or down by their respective pull up/down resistors. During power-down, the RESET/RESET output will be active when VCC falls below VTH. The RESET/RESET output will be valid so long as VCC is >1.0V (VRVALID). The device is designed to ignore the fast negative going VCC transient pulses (glitches). Reset output timing is shown in Figure 1. Manual Reset Operation The RESET pin can operate as reset output and manual reset input. The input is edge triggered; that is, the RESET input will initiate a reset timeout after detecting a high to low transition. When RESET I/O is driven to the active state, the 200 msec timer will begin to time the reset interval. If external reset is shorter than 200 ms, Reset outputs will remain active at least 200 ms. Glitches shorter than 100 ns on RESET input will not generate a reset pulse. Hardware Data Protection The CAT1320/21 family has been designed to solve many of the data corruption issues that have long been associated with serial EEPROMs. Data corruption occurs when incorrect data is stored in a memory location which is assumed to hold correct data. Whenever the device is in a Reset condition, the embedded EEPROM is disabled for all operations, including write operations. If the Reset output is active, in progress communications to the EEPROM are aborted and no new communications are allowed. In this condition an internal write cycle to the memory can not be started, but an in progress internal non-volatile memory write cycle can not be aborted. An internal write cycle initiated before the Reset condition can be successfully finished if there is enough time (5ms) before VCC reaches the minimum value of 2V. Figure 1.

D CAT1320, CAT1321 EMBEDDED EEPROM OPERATION The CAT1320 and CAT1321 feature a 32kbit embedded serial EEPROM that supports the I2C Bus data transmission protocol. This Inter-Integrated Circuit Bus protocol defines any device that sends data to the bus to be a transmitter and any device receiving data to be a receiver. The transfer is controlled by the Master device which generates the serial clock and all START and STOP conditions for bus access. Both the Master device and Slave device can operate as either transmitter or receiver, but the Master device controls which mode is activated. I2C Bus Protocol The features of the I2C bus protocol are defined as follows: (1) Data transfer may be initiated only when the bus is not busy. (2) During a data transfer, the data line must remain stable whenever the clock line is high. Any changes in the data line while the clock line is high will be interpreted as a START or STOP condition. START Condition The START Condition precedes all commands to the device, and is defined as a HIGH to LOW transition of SDA when SCL is HIGH. The CAT1320/21 monitors the SDA and SCL lines and will not respond until this condition is met. STOP Condition A LOW to HIGH transition of SDA when SCL is HIGH determines the STOP condition. All operations must end with a STOP condition. DEVICE ADDRESSING The Master begins a transmission by sending a START condition. The Master sends the address of the particular slave device it is requesting. The four most significant bits of the 8-bit slave address are programmable in metal and the default is 1010. The last bit of the slave address specifies whether a Read or Write operation is to be performed. When this bit is set to 1, a Read operation is selected, and when set to 0, a Write operation is selected. After the Master sends a START condition and the slave address byte, the CAT1320/21 monitors the bus and responds with an acknowledge (on the SDA line) when its address matches the transmitted slave address. The CAT1320/21 then performs a Read or Write operation depending on the R/W bit. Figure 4. Write Cycle Timing SCL SDA 8TH BIT BYTE n ACK tWR STOP CONDITION START CONDITION ADDRESS Doc. No. MD-3014, Rev. D 8 © 2009 SCILLC. All rights reserved. Characteristics subject to change without notice. CAT1320, CAT1321 ACKNOWLEDGE After a successful data transfer, each receiving device is required to generate an acknowledge. The acknowledging device pulls down the SDA line during the ninth clock cycle, signaling that it received the 8 bits of data. The CAT1320/21 responds with an acknowledge after receiving a START condition and its slave address. If the device has been selected along with a write operation, it responds with an acknowledge after receiving each 8bit byte. When the CAT1320/21 begins a READ mode it transmits 8 bits of data, releases the SDA line and monitors the line for an acknowledge. Once it receives this acknowledge, the CAT1320/21 will continue to transmit data. If no acknowledge is sent by the Master, the device terminates data transmission and waits for a STOP condition. WRITE OPERATIONS Byte Write In the Byte Write mode, the Master device sends the START condition and the slave address information (with the R/W bit set to zero) to the Slave device. After the Slave generates an acknowledge, the Master sends two 8-bit address bytes that are to be written into the address pointers of the device. After receiving another acknowledge from the Slave, the Master device transmits the data to be written into the addressed memory location. The CAT1320/ 21 acknowledges once more and the Master generates the STOP condition. At this time, the device begins an internal programming cycle to non-volatile memory. While the cycle is in progress, the device will not respond to any request from the Master device. Figure 5. Start/Stop Timing SDA SCL START BIT STOP BIT Figure 6.

D CAT1320, CAT1321 Page Write The CAT1320/21 writes up to 64 bytes of data in a single write cycle, using the Page Write operation. The page write operation is initiated in the same manner as the byte write operation, however instead of terminating after the initial byte is transmitted, the Master is allowed to send up to additional 63 bytes. After each byte has been transmitted, the CAT1320/21 will respond with an acknowledge and internally increment the lower order address bits by one. The high order bits remain unchanged. If the Master transmits more than 64 bytes before sending the STOP condition, the address counter ‘wraps around,’ and previously transmitted data will be overwritten. When all 64 bytes are received, and the STOP condition has been sent by the Master, the internal programming cycle begins. At this point, all received data is written to the CAT1320/21 in a single write cycle. Figure 8.

CAT1320, CAT1321 Acknowledge Polling Disabling of the inputs can be used to take advantage of the typical write cycle time. Once the stop condition is issued to indicate the end of the host’s write opration, the CAT1320/21 initiates the internal write cycle. ACK polling can be initiated immediately. This involves issuing the start condition followed by the slave address for a write operation. If the device is still busy with the write operation, no ACK will be returned. If a write operation has completed, an ACK will be returned and the host can then proceed with the next read or write operation. Read Operations The READ operation for the CAT1320/21 is initiated in the same manner as the write operation with one exception, that R/W bit is set to one. Three different READ operations are possible: Immediate/Current Address READ, Selective/Random READ and Sequential READ. Figure 10.

Characteristics subject to change without notice. 11 Doc No. MD-3014, Rev. D CAT1320, CAT1321 Immediate/Current Address Read The CAT1320 and CAT1321 address counter contains the address of the last byte accessed, incremented by one. In other words, if the last READ or WRITE access was to address N, the READ immediately following would access data from address N+1. For all devices, N=E=4,095. The counter will wrap around to Zero and continue to clock out valid data. After the CAT1320 and CAT1321 receives its slave address information (with the R/W bit set to one), it issues an acknowledge, then transmits the 8-bit byte requested. The master device does not send an acknowledge, but will generate a STOP condition. Selective/Random Read Selective/Random READ operations allow the Master device to select at random any memory location for a READ operation. The Master device first performs a ‘dummy’ write operation by sending the START condition, slave address and byte addresses of the location it wishes to read. After the CAT1320 and CAT1321 acknowledges, the Master device sends the START condition and the slave address again, this time with the R/W bit set to one. The CAT1320 and CAT1321 then responds with its acknowledge and sends the 8-bit byte requested. The master device does not send an acknowledge but will generate a STOP condition. Sequential Read The Sequential READ operation can be initiated by either the Immediate Address READ or Selective READ operations. After the CAT1320 and CAT1321 sends the inital 8-bit byte requested, the Master will responds with an acknowledge which tells the device it requires more data. The CAT1320 and CAT1321 will continue to output an 8-bit byte for each acknowledge, thus sending the STOP condition. The data being transmitted from the CAT1320 and CAT1321 is sent sequentially with the data from address N followed by data from address N+1. The READ operation address counter increments all of the CAT1320 and CAT1321 address bits so that the entire memory array can be read during one operation. Figure 11.
