EPSON
The CPU core built into this IC is an original 32-bit
RISC CPU from SEIKO EPSON. Regarding the CPU
core, refer to the S1C33208/204/202 Technical Manual
and S1C33 Family ASIC Macro Manual. The built-in
RAM is 8Kbytes.
Note: In the built-in CPU core, a DMA controller and
• Memory structure:
• Sector size:
• Unit of erase: Per chip or sector
• Unit of write: Writing with words
• Erase/write time:
• Access time:
• Reliability:
Flash ROM
Integration of a Flash ROM eliminated the necessity
of a ROM to externally store programs.
Others
A Boot ROM (4MBbytes, Max.) is connectable to
outside of this IC.
Supply voltage, 5.0V
