INDUSTRY-(Comparison of Performance)2. WHY PIC IS SO POPULAR?3. DIFFERENT PIC FAMILIES-A BRIEF COMPARISON

MICROPROCESSOR PERFORMANCE

• Intel 4004 - 0.092 MIPS at 740 kHz• Intel Pentium - 1.88 MIPS/MHz• AMD Athlon - 3561 MIPS @ 1.2 GHz• Intel Core Extreme-27,079 MIPS @ 2.93 GHz• Intel i7 - 113,093 MIPS @ 2.4 GHz

MAJOR PLAYERS IN MICROCONTROLLER INDUSTRY

• World’s First Microcontroller-TMS 1000 in 1971

• Created by Gary Boone and Michael Cochran

• A 4-bit device, 40+ varieties with varying amounts of RAM and ROM

• Very CHEAP- $2 per piece (bulk orders)• Highly Reliable- Claimed average life of

about 240 years!

• Intel’s First Microcontroller-MCS-48 series(8048 Family)

• 8 Bit Microcontrollers• 0.73 MIPS @ 11 MHz• Most Popular Series- MCS-51• 8051 Family • 1 MIPS @ 12 MHz

• Intel no longer manufactures microcontrollers

• Many companies still use 8051 architecture

• Many 8051 derivatives are available at < 100 INR

• Advanced Technology for MEmory and Logic• Major Microcontrollers include:– AVR Series( 8 and 32 Bit) MCU’s– ARM Based MCU’s– 8051 Derivatives

• AVR Series- First to use Flash memory for program Storage• Popular Because:– Cheap, Widely Available– Easy to Program- C compatible– Low Power Consumption

AVR MCU’s(8-32Bit)

•Up to 1.5 MIPS/MHz•Small Size•Low power Consumption

ARM BASED MCU’s

•32 Bit MCU’s•Up to 1 MIPS/MHz•Low Power Consumption

8051 Derivatives

•AT89 Series•AT89C1051 1K Flash Memory•Low Cost

• World’s largest manufacturer of MCU’s• RENaissancE Semiconductor for Advanced

Solutions• 8 ,16 and 32 Bit MCU’s available• Up to 2 MIPS/MHz Performance• Highly specific MCU’s ( Automotive, Phones etc)• Expensive

• One of the most popular MCU Brands• Spin-off from General Instruments• GI introduced microprocessor CP1600• First PIC MCU made to offload I/O tasks • PIC ( Peripheral Interface Controller ) Series

Why PIC?•Simple Instruction Set•Cheap• Starts at 50 INR•Easily available•Highly power efficient• Sleep current as low as 20nA• eXtreme Low Power (XLP) Technology•Easy to learn – Highly active forums on the web•Large User Base
