MB9B460L Series 32-Bit Arm Cortex -M4F FM4 Microcontroller Devices in the MB9B460L Series are highly integrated 32-bit microcontrollers with high performance and competitive cost. This series is based on the Arm Cortex -M4F Processor with on-chip Flash memory and SRAM. The series has peripheral 2 functions such as Motor Control Timers, ADCs and Communication Interfaces (CAN, UART, CSIO, I C, LIN). The products that are described in this datasheet are placed into TYPE2-M4 product categories in theFM4 Family Peripheral Manual Main Part (002-04856). Features 32-bit Arm Cortex -M4F Core SRAM This is composed of three independent SRAMs (SRAM0, Processor version: r0p1 SRAM1, and SRAM2). SRAM0 is connected to I-code bus and D-code bus of Cortex-M4F core. SRAM1 and SRAM2 are Up to 160 MHz Frequency Operation connected to System bus of Cortex-M4F core. FPU built-in SRAM0: Up to 32 Kbytes Support DSP instruction SRAM1: Up to 16 Kbytes Memory Protection Unit (MPU): improves the reliability of an SRAM2: Up to 16 Kbytes embedded system Integrated Nested Vectored Interrupt Controller (NVIC): 1 CAN Interface (1 Channel) NMI (non-maskable interrupt) and 128 peripheral interrupts and 16 priority levels Compatible with CAN Specification 2.0A/B 24-bit System timer (Sys Tick): System timer for OS task Maximum transfer rate: 1 Mbps management Built-in 32 message buffer On-Chip Memories Multi-Function Serial Interface (Max 6 Channels) Flash Memory 64 bytes with FIFO (the FIFO step numbers are variable These series are based on two independent on-chip Flash depending on the settings of the communication mode or bit memories. length.) MainFlash memory Operation mode is selectable from the followings for each Up to 512 Kbytes channel. Built-in Flash Accelerator System with 16 Kbytes trace UART buffer memory CSIO The read access to Flash memory can be achieved without LIN 2 wait-cycle up to operation frequency of 72 MHz. Even at I C the operation frequency more than 72 MHz, an equivalent access to Flash memory can be obtained by Flash UART Accelerator System. Full-duplex double buffer Security function for code protection Selection with or without parity supported Built-in dedicated baud rate generator WorkFlash memory External clock available as a serial clock 32 Kbytes Hardware Flow control : Automatically control the Read cycle: transmission by CTS/RTS (only ch.4) 6wait-cycle: the operation frequency more than 120 MHz, Various error detect functions available (parity errors, and up to 160 MHz framing errors, and overrun errors) 4wait-cycle: the operation frequency more than 72 MHz, and up to 120 MHz CSIO Full-duplex double buffer 2wait-cycle: the operation frequency more than 40 MHz, and up to 72 MHz Built-in dedicated baud rate generator Overrun error detect function available 0wait-cycle: the operation frequency up to 40 MHz Serial chip select function (ch.6 only) Security function is shared with code protection Supports high-speed SPI (ch.0 and ch.6 only) Data length 5 to 16-bit Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 002-04926 Rev.*B Revised December 15, 2017
