Unlock MCU PIC18F2539 Heximal

We can Unlock MCU PIC18F2539 Heximal, please view the MCU PIC18F2539 features for your reference:

This family offers the advantages of all PIC18 microcontrollers – namely, high computational performance at an economical price – with the addition of high-endurance Enhanced FLASH program memory. The PIC18FXX39 family also provides an off-the-shelf solution for simple motor control applications, allowing users to create speed control solutions with small part counts and short development times when Unlock MCU.

The integrated motor control kernel uses on-chip Pulse Width Modulation (PWM) to provide speed control for single phase induction motors. Through a convenient set of Application Program Interfaces (APIs) and variable frequency technology for open loop control, users can develop applications with little or no previous experience in motor control techniques if Unlock MCU.

ProMPT motor control provides modulated output over a range of 0 to 127 Hz, and has a pre-defined V/F curve that can be reprogrammed to suit the application before Unlock MCU.

· Memory Endurance: The Enhanced FLASH cells for both program memory and data EEPROM are rated to last for many thousands of erase/write cycles – up to 100,000 for program memory, and 1,000,000 for EEPROM. Data retention without refresh is conservatively estimated to be greater than 100 years at 25°C after Unlock MCU.

· Self-programmability: These devices can write to their own program memory spaces under internal software control. By using a bootloader routine located in the protected Boot Block at the top of program memory, it becomes possible to create an application that can update itself in the field if Unlock MCU.

· Addressable USART: This serial communication module is capable of standard RS-232 operation using the internal oscillator block, removing the need for an external crystal (and its accompanying power requirement) in applications that talk to the outside world when Unlock MCU.

· 10-bit A/D Converter: This module offers up to 8 conversion channels for flexibility in sensor monitoring and control, as well as the ability to do conversions while the device is in SLEEP mode.

Devices in the PIC18FXX39 family are available in 28-pin (PIC18F2X39) and 40/44-pin (PIC18F4X39) packages. Block diagrams for the two groups are shown in Figure 1-1 and Figure 1-2 before Unlock MCU.

The devices are differentiated from each other in four ways:

1. FLASH program memory and data RAM (12 Kbytes and 640 bytes for PIC18FX439 devices, 24 Kbytes and 1408 bytes for PIC18FX539)

2. A/D channels (5 for PIC18F2X39 devices, 8 for PIC18F4X39)

The EC and ECIO Oscillator modes require an external clock source to be connected to the OSC1 pin. The feedback device between OSC1 and OSC2 is turned off in these modes to save current. There is no oscillator start-up time required after a Power-on Reset or after a recovery from SLEEP mode after Unlock MCU.

In the EC Oscillator mode, the oscillator frequency divided by 4 is available on the OSC2 pin. This signal may be used for test purposes or to synchronize other logic. Figure 2-3 shows the pin connections for the EC Oscillator mode if Unlock MCU.
