Flash Memory/EEPROM
Serial EEPROM Advantages
- SANYO develops and supplies highly reliable EEPROM that can also be customized.
1st Stage: Standard 2-wire/3-wire Serial EEPROM
2nd Stage: Customer-oriented Serial EEPROM - Development of EEPROM to meet miniaturization needs
- We meet needs for use in ultraminiature packages, provide products as WLCSPs, and support wafer shipments. - We provide low-capacity nonvolatile memory with functions optimized for the application.
- We take the initiative in sales of products in sets that include analog IC products, such as microcontrollers and TV tuners.
Examples of EEPROM Applications

Custom EEPROM
SANYO Semiconductor also develops custom EEPROM to meet customer needs.
EEPROM Supporting Boot Transfer
SANYO custom EEPROM serve as the master device when power is supplied, controlling the system bus and initializing slave devices connected to the bus. (After sending initialization data, the EEPROM function as slave memory) → Also effective for correction or compensation in analog systems.
SANYO custom EEPROM can automatically transfer data when power is supplied.

Usage Example: CCD Device Compensation
CCD System Optimization without a Microprocessor
- 1. Compensation data is stored in the EEPROM in advance.
- 2. When power is supplied, data is sent to the device for compensation, using the boot transfer function.
- 3. Next, the EEPROM product serves as a slave device in standby state.
Tiny Packages
To meet needs for exceptionally small packages, we can also provide even smaller and thinner packages.
