STM8S105C4T6TR
Category: 8 Bit Microcontrollers STMicroelectronics
STMicroelectronics The STM8S105x4/6 access line 8-bit microcontrollers offer from 16 to 32 Kbyte Flash program memory, plus integrated true data EEPROM. The STM8S microcontroller family reference manual (RM0016) refers to devices in this family as medium-density. All devices of the STM8S105x4/6 access line provide the following benefits: reduced system cost, performance and robustness, short development cycles, and product longevity.The system cost is reduced thanks to an integrated true data EEPROM for up to 300 k write/erase cycles and a high system integration level with internal clock oscillators, watchdog and brown-out reset.Device performance is ensured by a 16 MHz CPU clock frequency and enhanced characteristics which include robust I/O, independent watchdogs (with a separate clock source), and a clock security system.Short development cycles are guaranteed due to application scalability across common family product architecture with compatible pinout, memory map and modular peripherals.Product longevity is ensured in the STM8S family thanks to their advanced core which is made in a state-of-the-art technology for applications with 2.95 V to 5.5 V operating supply.

ATMEGA64A-AU
Category: 8 Bit Microcontrollers , MCUs Microchip
Microchip 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 ATmega64A provides the following features: 64 Kbytes In-System Programmable Flash with ReadWhile- Write capabilities, 2 Kbytes EEPROM, 4 Kbytes SRAM, 53 general purpose I/O lines, 32 general purpose working registers, Real Time Counter (RTC), four flexible Timer/Counters with compare modes and PWM, two USARTs, a byte oriented Two-wire Serial Interface, an 8-channel, 10-bit ADC with optional differential input stage with programmable gain, programmable Watchdog Timer with internal Oscillator, an SPI serial port, IEEE std. 1149.1 compliant JTAG test interface, also used for accessing the On-chip Debug system and programming, and six software selectable power saving modes. 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 Power-save mode, the asynchronous timer continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping. The ADC Noise Reduction mode stops the CPU and all I/O modules except asynchronous timer and ADC, to minimize switching noise during ADC conversions. 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. In Extended Standby mode, both the main Oscillator and the asynchronous timer continue to run. Packaging: TRYSupplier Type: Authorized Distributor112 Qty Price 90 6.5472 100 5.9272
