Microchip Technology AT90S85354JC Microcontroller

The AT90S85354JC from Microchip Technology is a high-performance, low-power 8-bit AVR RISC-based microcontroller that combines 8KB ISP flash memory with read-while-write capabilities, 512 bytes of EEPROM, 512 bytes of SRAM, 32 general-purpose I/O lines, 32 general-purpose working registers, a JTAG interface for boundary-scan and on-chip debugging/programming, and five software-selectable power-saving modes. This versatile microcontroller is designed to offer an efficient solution for embedded systems.

Key Features:

• Advanced RISC Architecture: With 131 powerful instructions, most of which are executed in a single clock cycle, the AT90S85354JC achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
• In-System Programmable Flash: The device boasts 8KB of in-system programmable flash, allowing the program memory to be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile memory programmer.
• JTAG (IEEE 1149.1 Compliant) Interface: The inclusion of JTAG enables on-chip debugging and programming, making development simpler and more efficient.
• Power Efficiency: Five different power-saving modes provide options to reduce power consumption for various operation conditions. These modes include Idle, ADC Noise Reduction, Power-save, Power-down, and Standby.
• I/O and Packages: 32 programmable I/O lines are available, and the device comes in a 44-lead TQFP (Thin Quad Flat Pack) and a 44-pad QFN/MLF (Quad Flat No-leads/Micro Lead Frame).
• Peripheral Features: Two 8-bit timer/counters with separate prescalers and compare modes, one 16-bit timer/counter with separate prescaler, compare mode, and capture mode, Real Time Counter with separate oscillator, three PWM channels, and a serial programmable USART.
• Operating Voltages: The microcontroller operates between 4.5-5.5V, making it suitable for 5V logic level systems.
