Crack IC ATmega8515 memory and extract MCU Program out from its flash memory, and data from its eeprom memory, chemical solution can be applied for removal of silicon package over the cap of Microcontroller ATmega8515 in order to get access to its databus by reverse engineering MCU;
The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle.
The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
The ATmega8515 provides the following features: 8K bytes of In-System Programmable Flash with Read-While-Write capabilities, 512 bytes EEPROM, 512 bytes SRAM, an External memory interface, 35 general purpose I/O lines, 32 general purpose working registers, two flexible Timer/Counters with compare modes, Internal and External interrupts, a Serial Programmable USART, a programmable Watchdog Timer with internal Oscillator, a SPI serial port, and three software selectable power saving modes after Microchip MCU PIC16F871 content reading.
The Idle mode stops the CPU while allowing the SRAM, Timer/Counters, SPI port, and Interrupt system to continue functioning. The Power-down mode saves the Register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or hardware reset. In Standby mode, the crystal/resonator Oscillator is running while the rest of the device is sleeping. This allows very fast start-up combined with low-power consumption before Microchip MCU PIC16C54C code restoration.
The device is manufactured using Atmel’s high density nonvolatile memory technology. The On-chip ISP Flash allows the Program memory to be reprogrammed In-System through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core.
The boot program can use any interface to download the application program in the Application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation.
By combining an 8-bit RISC CPU with In-System Self-programmable Flash on a monolithic chip, the Atmel ATmega8515 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.
The ATmega8515 is supported with a full suite of program and system development tools including: C Compilers, Macro assemblers, Program debugger/simulators, In-circuit Emulators, and Evaluation kits. Typical values contained in this datasheet are based on simulations and characterization of other AVR microcontrollers manufactured on the same process technology.
Min and Max values will be available after the device is characterized.
