Product details

48 MHz Cortex-M0 — enough for BLE + sensor fusion

The CY8C4248LQI-BL583T: The 48 MHz ARM Cortex-M0 core handles the Bluetooth LE stack and CapSense processing load.

Bluetooth and CapSense — the key integrated peripherals

This part includes an integrated Bluetooth LE radio, CapSense touch-sensing hardware, brown-out detect, POR, LVD, PWM, and a SmartCard interface.

56-QFN 7x7 mm — footprint and thermal considerations

The device is housed in a 56-UFQFN exposed-pad package (7x7 mm body).

It is ROHS3 compliant and remains in volume production with no announced last-time-buy.

Frequently asked questions

What is the equivalent part for CY8C4248LQI-BL583T?

The closest functional second-source within the same PSoC 4 BLE family is the CY8C4247LQI-BL473. It shares the same ARM Cortex-M0 core at 48 MHz, the same 56-QFN 7x7 mm package, 36 I/O, and the same connectivity and peripheral set including Bluetooth and CapSense. The main difference is Flash size: 128 KB on the CY8C4247 versus 256 KB on the CY8C4248, and the ADC is 8x12b instead of 16x12b. If your firmware fits in 128 KB, it is a drop-in alternate.

Does CY8C4248LQI-BL583T support Bluetooth 5.0?

No, the Bluetooth peripheral integrated in this MCU is Bluetooth 4.2 compliant. It does not support Bluetooth 5.0 features such as 2 Mbps PHY, long-range coding (Coded PHY), or extended advertising. For Bluetooth 5.0 capability, consider the PSoC 6 series (e.g. CY8C6137BZI-F54) which runs a Cortex-M4 at 150 MHz and includes a BLE 5.0 radio, though it is a different package and pinout.
