SF32LB52X
SF32LB52X
SF32LB52x/X:
- x represents a number and belongs to the lithium-ion battery-powered series, such as SF32LB520/3/5/7, which are pin-to-pin compatible with each other.
- X represents certain letters and belongs to the standard 3.3V-powered series, including SF32LB52B/E, which are pin-to-pin compatible with each other.
- X represents certain letters and belongs to the special 1.8V-powered series, including SF32LB52A/D, intended for ultra-low-power applications.
- The two series, where x is a digit and X is a letter, are independent and not pin-to-pin compatible. Although the 3.3V and 1.8V models can align pin-to-pin, they are not voltage-compatible and therefore not compatible. The corresponding relationships based on co-packaged content are as follows:
- Battery ?3.3V ?1.8V
- 520 – 52B
- 523 – 52E – 52D
- 525 – 52G
- 527 – 52J
The SF32LB52x series supports the following display interfaces:
- SPI/DSPI/QSPI, including an SPI interface for e-ink displays
- 8080-8bit
