89E516RD2
The SST89E5xxRD2 and SST89V5xxRD2 are FlashFlex51 family 8-bit microcontroller devices designed and manufactured using SST's unique and proprietary Super Flash CMOS semiconductor manufacturing technology. SST's clients gain significantly from the split-gate device structure and thick-oxide tunnelling injector in terms of cost and reliability. The devices are pin-for-pin compatible with ordinary 8051 microcontroller devices and use the 8051 instruction set. The devices include 16/24/40/72 K Byte of on-chip flash EEPROM programme memory that is divided into two separate programme memory blocks. The primary Block 0 has 8/16/32/64K Bytes of internal programme memory space, whereas the secondary Block 1 has 8K Bytes of internal programme memory space.
The 8-KByte secondary block can be identified to the minimum address point in the 8/16/32/64 K Byte address space, as well as concealed from the programme counter and utilised as an independent EEPROM-like data store. In addition to the on-chip EEPROM programme memory of 16/24/40/72 K Bytes, the devices may address up to 64 K Bytes of external programme memory. In addition to 1024 x 8 bits of on-chip RAM, external RAM of up to 64 K Bytes may be addressed.

AT24C512 Datasheet
AT24C512C-SSHD
The AT24C512C functions as a slave device and communicates with a host controller, also known as the bus master, using a straightforward two-wire digital serial interface that is I2C-compatible. On a serial bus, the master initiates and manages all read and write operations to slave devices, and both the master and slave devices are capable of sending and receiving data. Just two signal lines?Serial Clock (SCL) and Serial Data?make up the serial interface (SDA). The bilateral SDA pin is used to receive command and detailed empirical from the master as well as to transmit data back to the master, while the SCL pin is used to accept the clock signal from the master. To reduce the impact of input spikes and bus noise, the SCL and SDA pins each include Schmitt Triggers and inbuilt spike suppression filters. The Most Significant bit (MSb) is always transmitted first when sending commands or data. After eight bits (one byte) of information have been exchanged during bus communication, the receiving device must answer with an Acknowledge (ACK) or No-Acknowledge (NACK) response bit during such a ninth clock cycle (ack/nack clock cycle) produced by the master. As a result, nine clock cycles are needed to send one byte of data. There must be no gaps or interruptions throughout any data transfer operation since there are no spare clock cycles.
