如果您希望可以时常见面，欢迎标星收藏哦~ 来源 ：内容来自 eenewseurope 。 Raspberry Pi 已推出其多核 RP2350 微控制器的第三个版本，以解决该芯片的许多性能和安全问 题，并为工业应用添加 5V 支持。 新 版 本 RP2350 A4 同 时 具 有 ARM 和 RISC-V 内 核 ， 由 首 席 执 行 官 Eben Upton 在 eeNews Europe Elektor 供应链问题现场圆桌会议上宣布。 RP2350 的首发版本 A2 存在 GPIO 焊盘设计错误，导致焊盘无法正常进入高阻状态，并且存在 RP2350 黑客挑战赛参与者发现的一系列安全问题。这些问题已通过 A4 版本中对金属层的最新改 进得到解决。 Upton 表示："我们对焊盘宏进行了细微调整，以消除焊盘高端的不良漏电；这种漏电会导致下方 A2 的电流-电压曲线出现较大的负向偏移。因此，不再需要外部电阻来拉低输入，尽管在现有设计 中可以安全地保留它们。" RP2350 黑客挑战赛中发现的 Boot ROM 安全漏洞已在 A4 启动 ROM 中得到修复，此外，还实 施了多种新的防御策略，以降低未来被攻击的可 ...

Core Viewpoint - Raspberry Pi has launched the RP2350 microcontroller, which features significant improvements in performance, security, and power efficiency compared to its predecessor, the RP2040 [1][2][3]. Pricing and Availability - The RP2350A (7×7 QFN60) is priced at $1.10 per unit, while the RP2350B (10×10 QFN80) is priced at $1.20 per unit. Bulk purchases significantly reduce the price, with the RP2350A available for $0.80 per unit when buying 3,400 units [1][2]. - The RP2354A and RP2354B models, which will include 2MB stacked flash memory, are in the final stages of development and testing, with plans for mass production later this year [1][5]. Technical Specifications - The RP2350 integrates dual Arm Cortex-M33 processors running at 150MHz, supporting floating-point operations and DSP, along with a security model based on Arm TrustZone [3][4]. - The microcontroller features enhanced power efficiency, with the ability to reduce power consumption to less than one-tenth of the previous model when in low-power mode [3][4]. Design Improvements - The RP2350 replaces the voltage regulator with a more efficient converter, allowing for higher peak current delivery and improved efficiency in low-power modes [4]. - The design retains many elements from the RP2040, allowing for quicker integration and development while also introducing new features such as OTP and core power regulation [5].
