HPMICRO HPM5E31IGN1

The HPM5E00 series is a high-performance microcontroller featuring a 32-bit RISC-V processor with RV32-IMAFDCBP instruction set support and an integrated DSP unit with SIMD and DSP instruction support. The series is equipped with 32KB L1 instruction cache and 32KB L1 data cache, along with 128KB instruction local memory and 128KB data local memory. On-chip memory resources include 544KB SRAM, 1MB embedded flash, 4096-bit OTP, and 128KB BOOT ROM. The system integrates real-time Ethernet functionality, including an EtherCAT slave controller and a Gigabit Ethernet controller. Power management supports multiple modes — run, wait, stop, sleep, and shutdown — with multiple on-chip power supplies integrated. The clock system provides a 24MHz crystal oscillator, 24MHz and 32KHz internal RC oscillators, and 3 PLLs with fractional divider and spread spectrum support. External memory interfaces include a serial bus controller and a programmable parallel bus. Motion control peripherals include 2 PWM modules, quadrature encoder input/output interface, 4-channel ΣΔ signal receiver unit, and a programmable logic module. Timer resources include 5 groups of 32-bit general-purpose timers and 3 watchdog timers. Communication interfaces are comprehensive, including 9 UARTs, 4 SPIs, 4 I2Cs, 1 USB2.0 OTG, 4 CAN controllers, and 2 1-Wire controllers. Analog peripherals include 2 16-bit/2MSPS ADCs and 2 analog comparators. The I/O section provides 148 GPIOs supporting 3.3V and 1.8V logic levels, along with an extended HMI interface and an IO logic observation module. Additionally, information security features are integrated, with NOR Flash real-time decryption support.
