• Programmable code protection
• Power saving SLEEP mode
• Single supply 5V In-Circuit Serial Programming™ (ICSP™) via two pins
• In-Circuit Debug (ICD) via two pins
• Compatible 10-bit Analog-to-Digital Converter module (A/D) with:
- Fast sampling rate
- Conversion available during SLEEP
- DNL = ±1 LSb, INL = ±1 LSb
• Programmable Low Voltage Detection (PLVD)
- Supports interrupt on Low Voltage Detection
• Programmable Brown-out Reset (BOR)
• High current sink/source 25 mA/25 mA
• Three external interrupt pins
• Timer0 module: 8-bit/16-bit timer/counter with 8-bit programmable prescaler
• Timer1 module: 16-bit timer/counter
• Timer3 module: 16-bit timer/counter
• Secondary oscillator clock option - Timer1/Timer3
• Two PWM modules:
- Resolution is 1- to 10-bit, Max. PWM freq. @ 8-bit resolution = 156 kHz 10-bit resolution = 39 kHz
• Single Phase Induction Motor Control kernel
- Programmable Motor Control Technology (ProMPT™) provides open loop Variable Frequency (VF) control
- User programmable Voltage vs. Frequency curve
- Most suitable for shaded pole and permanent split capacitor type motors
• Master Synchronous Serial Port (MSSP) module with two modes of operation:
- 3-wire SPI™ (supports all 4 SPI modes)
- I2C™ Master and Slave mode
• Addressable USART module:
- Supports RS-485 and RS-232
• Parallel Slave Port (PSP) module


Application

`The Motor Control kernel allows users to develop their applications without having knowledge of motor control.

`The key parameters of the motor control kernel can be set and read through the Application Program Interface (API) methods discussed in the previous section.

`The overall application can be thought of as a protocol stack, as shown in Figure 14-3. In this case, the API methods reside between the user's application and the ProMPT kernel, and are used to exchange parameter values. The motor control kernel sets the PWM duty cycles based on the inputs from the application software.

`A typical motor control routine is shown in Example 14-1. In this case, the motor will run at 20 Hz for 10 seconds, accelerate to 60 Hz at the rate of 10 Hz/s, remain at 60 Hz for 20 seconds, and finally stop.

Specifications

Ambient temperature under bias -55 to +125
Storage temperature -65 to +150
Voltage on any pin with respect to VSS (except VDD, MCLR, and RA4) -0.3V to (VDD + 0.3V)
Voltage on VDD with respect to VSS -0.3V to +7.5V
Voltage onMCLRwith respect to VSS (Note 2) 0V to +13.25V
Voltage on RA4 with respect to Vss 0V to +8.5V
Total power dissipation (Note 1) 1.0W
Maximum current out of VSS pin 300 mA
Maximum current into VDD pin 250 mA
Input clamp current, IIK (VI < 0 or VI > VDD) ±20 mA
Output clamp current, IOK (VO < 0 or VO > VDD) ±20 mA
Maximum output current sunk by any I/O pin 25 mA
Maximum output current sourced by any I/O pin 200 mA
Maximum current sunk by PORTA, PORTB, and PORTE (Note 3) (combined) 200 mA
Maximum current sourced by PORTA, PORTB, and PORTE (Note 3) (combined) 200 mA
Maximum current sunk by PORTC and PORTD (Note 3) (combined) 200 mA
Maximum current sourced by PORTC and PORTD (Note 3) (combined) 200 mA
Note 1: Power dissipation is calculated as follows:
             Pdis = VDD x {IDD - IOH} + {(VDD-VOH) x IOH} + (VOl x IOL)
2: Voltage spikes below VSS at the MCLR/VPP pin, inducing currents greater than 80 mA, may cause latTchup.Thus, a series resistor of 50-100 should be used when applying a "low" level to the MCLR/VPP pin, rather
than pulling this pin directly to VSS.
3: PORTD and PORTE not available on the PIC18F2X39 devices.
