Infineon CY9BF122LQN-G-AVERE2

The CY9B120M Series are highly integrated 32-bit microcontrollers dedicated for embedded controllers with low-power consumption mode and competitive cost. These series are based on the Arm Cortex-M3 Processor with on-chip Flash memory and SRAM, and have peripheral functions such as various timers, ADCs, DACs and Communication Interfaces (UART, CSIO, I2C, LIN).

• Processor version: r2p1
• Up to 72 MHz Frequency Operation

• 24-bit System timer (Sys Tick): System timer for OS task management
• Dual operation Flash memory: Dual Operation Flash memory has the upper bank and the lower bank. So, this series could implement erase, write and read operations for each bank simultaneously. Main area: Up to 256 Kbytes (Up to 240 Kbytes upper bank + 16 Kbytes lower bank). Work area: 32 Kbytes (lower bank)
• Read cycle: 0 wait-cycle
• Security function for code protection
• This Series on-chip SRAM is composed of two independent SRAM (SRAM0, SRAM1). SRAM0 is connected to I-code bus and D-code bus of Cortex-M3 core. SRAM1 is connected to System bus.
• SRAM0: Up to 16 Kbytes
• SRAM1: Up to 16 Kbytes
• Multi-function Serial Interface (Max eight channels): 4 channels with 16 stepsx9-bit FIFO (ch.0/1/3/4), 4 channels without FIFO (ch.2/5/6/7)
• Operation mode is selectable from the followings for each channel: UART, CSIO, LIN, I2C
• UART: Full duplex double buffer, Selection with or without parity supported, Built-in dedicated baud rate generator, External clock available as a serial clock, Hardware Flow control: Automatically control the transmission/reception by CTS/RTS (only ch.4), Various error detection functions available (parity errors, framing errors, and overrun errors)
• CSIO: Full duplex double buffer, Built-in dedicated baud rate generator, Overrun error detection function available
• LIN: LIN protocol Rev.2.1 supported, Full duplex double buffer, Master/Slave mode supported, LIN break field generation (can be changed to 13 to 16-bit length), LIN break delimiter generation (can be changed to 1 to 4-bit length), Various error detection functions available (parity errors, framing errors, and overrun errors)
• I2C: Standard mode (Max 100 kbps)/Fast mode (Max 400 kbps) supported
• DMA Controller (Eight channels): The DMA controller has an independent bus from the CPU, so the CPU and the DMA controller can process simultaneously. 8 independently configured and operated channels, Transfer can be started by software or request from the built-in peripherals, Transfer address area: 32-bit (4 Gbytes), Transfer mode: Block transfer/Burst transfer/Demand transfer, Transfer data type: bytes/half-word/word, Transfer block count: 1 to 16, Number of transfers: 1 to 65536
• 12-bit A/D Converter: Successive Approximation type, Built-in 2 units, Conversion time: 0.8 μs @ 5V, Priority conversion available (priority at 2 levels), Scanning conversion mode, Built-in FIFO for conversion data storage (for SCAN conversion: 16 steps, for Priority conversion: 4 steps)
• D/A Converter (Max two channels): R-2R type, 10-bit resolution
• Base Timer (Max eight channels): Operation mode is selectable from the followings for each channel: 16-bit PWM timer, 16-bit PPG timer, 16-/32-bit reload timer, 16-/32-bit PWC timer
• This series can use its pins as general-purpose I/O ports when they are not used for peripherals. Moreover, the port relocate function is built in. It can set which I/O port the peripheral function can be allocated to.
• Capable of pull-up control per pin
• Capable of reading pin level directly
• Built-in port relocate function
• Up to 65 high-speed general-purpose I/O ports @ 80 pin package
• Some ports are 5V tolerant.
• Dual Timer (32-/16-bit Down Counter): The dual timer consists of two programmable 32-/16-bit down counters. Operation mode is selectable from the followings for each channel: Free-running, Periodic (= Reload), One-shot
• The Quadrature Position/Revolution Counter (QPRC) is used to measure the position of the position encoder. Moreover, it is possible to use as the up/down counter.
• The detection edge of the three external event input pins AIN, BIN and ZIN is configurable.
• 16-bit position counter
• 16-bit revolution counter
• Two 16-bit compare registers
• Multi-Function Timer: The multi-function timer is composed of the following blocks: 16-bit free-run timer × 3ch./unit, Input capture × 4ch./unit, Output compare × 6ch./unit, A/D activation compare × 2ch./unit, Waveform generator × 3ch./unit, 16-bit PPG timer × 3ch./unit
