Description

YFS1544 series mainly consists of PFS154 and 2K-bit EEPROM：
● PFS154 MCU
● 2K-bit EEPROM

Among them, PFS154 is an IO type MTP MCU, supporting Mini-C / ASM language, easy to program.
For details on the use of PFS154, please refer to the "PFS154 Datasheet" on PADAUK’s official website.
The built-in 2K-bit EEPROM, as an I2C-compatible serial EEPROM (electrically erasable programmable
memory) device, contains a 256×8-bit memory array with 8 bytes per page, which can provide more data
storage for the MCU Take space.
