... And when data of the maximum bytes or higher is sent, data from the first byte is overwritten. (Refer to "Internal address increment" of "Notes on page write cycle" in P16.) ・As for page write cycle of BR24G32-3A, after the significant 7 bits of word address is designated arbitrarily, by continuing data input of 2 bytes or more, the address of insignificant 5 bits is incremented internally, and data bytes can be written ...
Page 16
... The above numbers are maximum bytes for respective types. Any bytes below these can be written. In the case BR24G32-3A, 1 page=32bytes, but the page write cycle time is 5ms at maximum for 32byte bulk write. It does not stand 5ms at maximum × 32byte=160ms(Max.) ○Internal address increment ...

... BR24G32-3A ●Read Command ○Read cycle Data of EEPROM is read. In read cycle, there are random read cycle and current read cycle. Random read cycle is a command to read data by designating address, and is used generally. Current read cycle is a command to read data of internal address register without designating address, and is used when to verify just after write cycle ...

... BR24G32-3A ●Software reset Software reset is executed when to avoid malfunction after power on, and to reset during command input. Software reset has several kinds, and 3 kinds of them are shown in the figure below. (Refer to Fig.41-(a), Fig.41-(b), Fig.41-(c).) In dummy clock input area, release the SDA bus ('H' by pull up). In dummy clock area, ACK output and read data '0' (both 'L' level) may be output from EEPROM, therefore, if 'H' is input forcibly, output may conflict and over current may flow, leading to instantaneous power failure of system power source or influence upon devices ...

... BR24G32-3A ●WP valid timing (write cancel usually fixed to 'H' or 'L', but when WP is used to cancel write cycle and so forth, pay attention to the following WP valid timing. During write cycle execution, in cancel valid area, by setting WP='H', write cycle can be cancelled. In both byte write cycle and page write cycle, the area from the first start condition of command to the rise of clock to taken data(in page write cycle, the first byte data) is cancel invalid area ...

... BR24G32-3A ●I/O peripheral circuit ○Pull up resistance of SDA terminal SDA is NMOS open drain, so requires pull up resistance. As for this resistance value (R this resistance value from microcontroller V limited. The smaller the R , the larger the consumption current at action. PU ○Maximum value The maximum value determined by the following factors. ...
Page 21
... BR24G32-3A ●Cautions on microcontroller connection ○ BUS recommended that SDA port is of open drain input/output. However, when to use CMOS input / output of tri state to SDA port, insert a series resistance Rs between the pull up resistance Rpu and the SDA terminal of EEPROM. This is controls over current that occurs when PMOS of the microcontroller and NMOS of EEPROM are turned ON simultaneously ...

BR24G32-3A 2 ●I C BUS Input / Output Circuit ○Input (A0, A1, A2, SCL, WP) Fig.50 Input pin circuit diagram ●Notes on Power ON At power on internal circuit and set, Vcc rises through unstable low voltage area, and IC inside is not completely reset, and malfunction may occur. To prevent this, functions of POR circuit and LVCC circuit are equipped. To assure the action, observe the following conditions at power on. 1. Set SDA = 'H' and SCL ='L' or 'H’ ...

(2) We believe that application circuit examples are recommendable, however, in actual use, confirm characteristics further sufficiently. In the case of use by changing the fixed number of external parts, make your decision with sufficient margin in consideration of static characteristics and transition characteristics and fluctuations of external parts and our LSI ...
