Key Features
- 64 MHz operation with eXtreme Low Power (XLP) sleep current below 20 nA, combining high throughput and ultra-low standby power in one device
- Dual Enhanced SSP modules (SPI + I2C) and 2 ECCP channels enable simultaneous multi-channel communication and precision PWM motor control
- 12-channel 12-bit ADC with on-chip temperature indicator, supporting precision multi-sensor acquisition from a 2.3 V to 5.5 V supply
Applications
PIC18F25K22-E/SS targets HVAC controllers, smart metering front ends, and multi-axis servo drivers requiring both high-speed 64 MHz control loops and ultra-low 20 nA sleep current between sampling events. The dual serial modules and enhanced PWM outputs also make it a strong fit for industrial pump controllers, solar charge regulators, and wired sensor networks using I2C daisy-chained to multiple measurement nodes.

Frequently Asked Questions
What is the minimum supply voltage for PIC18F25K22-E/SS and how does it affect clock speed?
PIC18F25K22-E/SS operates from a minimum of 2.3 V at which it runs up to 16 MHz. Raising the supply to 2.7 V enables 32 MHz operation, and the full 64 MHz is achievable at 3.0 V to 5.5 V. This graduated voltage-speed relationship allows the device to track battery discharge in portable designs, stepping down frequency as the cell voltage drops while remaining operational above 2.3 V.
How do the dual ECCP modules in PIC18F25K22-E/SS support half-bridge or full-bridge motor drive circuits?
Each Enhanced Capture/Compare/PWM (ECCP) module can generate complementary PWM outputs with programmable dead-band delay of 0 to 127 instruction cycles, enabling half-bridge gate drive directly from the microcontroller without external dead-band logic. At 64 MHz the minimum dead-band resolution is about 62.5 ns, which is sufficient for most MOSFET switching times of 100 ns to 1 µs in motor control applications up to 20 kHz PWM frequency.
How does the 12-channel 12-bit ADC in PIC18F25K22-E/SS improve over the 10-bit ADC in earlier PIC18F25K20?
The 12-bit ADC provides 4,096 steps versus 1,024 steps on the 10-bit ADC, improving measurement resolution by a factor of 4. On a 3.3 V reference this gives approximately 0.8 mV per LSB compared to 3.2 mV per LSB, making the PIC18F25K22-E/SS more accurate for current sensing, thermocouple linearisation, and pressure transducer readings where the previous 10-bit resolution introduced unacceptable quantisation error.
What sleep current does PIC18F25K22-E/SS achieve and how does that compare to standard PIC18 devices for battery-powered meters?
Using XLP (eXtreme Low Power) mode, PIC18F25K22-E/SS achieves a sleep current below 20 nA at 1.8 V — roughly 50x lower than standard PIC18 devices that typically draw 1 µA or more. For a smart meter sampling once per second with a 1 ms active window at 1 mA, the average current is approximately 1.02 µA using XLP sleep versus 2 µA or more with a standard PIC18, nearly doubling battery life on a CR2032 coin cell.
