Iyalin gidan Renesas Cortex-M MCU suna ƙara tsaro don IoT da kuma goyon bayan yanayin ƙasa

Wanda ake kira dangin RA, suna PSA Certified Level 1 kuma sunzo a jerin guda hudu:

• Jerin RA2 - Cortex-M23 har zuwa 60 MHz
• Jerin RA4 - Cortex-M4 har zuwa 48MHz (ko 100MHz, kamfanin yace duka biyu)
• Jerin RA6 - Cortex-M4 har zuwa 120MHz (har zuwa 200 MHz)
• RA8 Jerin - don sakewa daga baya - ualauka biyu 200MHz

Wannan ya yi kama da dangin Renesas na yanzu da suka kasance 'RCC' Synergy '?

Yana yin hakan, ya yarda da darektan tallace-tallace na Renesas Tim Burgess, amma za a iya amfani da Synergy MCUs tare da ƙwararrun masaniyar kayan aikin da kayan masarufi - tare tare da samar da '' Syn Syn Platform '- yayin da za'a iya amfani da kayan aiki na ɓangare na uku tare da kayan aikin RA.

Amma shin silicon iri ɗaya ne?

"Ba za mu bayyana wannan ba," in ji Burgess ga Watan Lantarki, ya kuma kara da cewa: "Akwai da yawa sabon sabbin na'urorin RA da ke zuwa wanda ba za ku samu kama da na na'urar hadin gwiwar ba."

Don RA MCUs, Renesas ya haɗu da abokan haɗin gwiwa don sadar da software da kayan aikin don tallafa musu.

"Shirin samar da kayan kwalliya na RA Family 'mai samarda kayan aiki mai sassauci' [FSP] yana ba da tsarin gine-ginen da ke ba abokan ciniki damar sake amfani da lambar kayan aikin su kuma hada shi tare da misalai na software daga Renesas da abokan haɗin lafiyar yanayin don yin saurin aiwatar da ayyuka masu rikitarwa kamar haɗi da tsaro," in ji zuwa Renesas. "FSP yana dauke da Amazon FreeRTOS kuma za ta ƙara tallafi daga akwatin-akwatin don threadX RTOS da kayan tsakiya a kan Cortex-M23 da Cortex-M33 MCUs a farkon 2020, suna ba da zaɓi na kayan-in-girgije ga masu haɓaka. Za'a iya sauƙaƙe waɗannan zaɓuɓɓukan daga cikin akwatin da sauƙaƙe tare da kowane RTOS ko na'urar tsakiya. ”

Layin farko - RA8 da Cortex-M33 na'urorin sun zo daga baya

32 RA MCUs an sake su a yau, cikin rukuni biyar, sun rarrabu tsakanin jerin uku - a cikin harshen Renesas.

Suna bayar da zaɓi na Cortex-M4 ko Cortex-M23, ƙididdigar kunshin-girma daga 32 zuwa 176, tsakanin 256kbyte da 2Mbyte na walƙiya, kuma daga 32 zuwa 640kbyte na RAM.

Zaɓuɓɓukan haɗi sun haɗa da USB, CAN, Ethernet da firikwensin taɓawar taɓawa.

A cikin 2020, kundin tsarin hanya yana ƙaddara ƙarin na'urori masu haɓaka da suka hada da bangarorin dual-core RA8 da zaɓin Cortex-M33.

"Hanyar hanya tana ba PSA ingantacciya da Amintattun Firmware-M [TF-M] masu yarda da API, ciki har da Cortex-M33 MCUs, low-power Cortex-M23 MCUs, da kuma IEE 802.15.4 mara waya IIT samfuri," in ji Renesas. "MCUs tare da takaddun shaida na TF-M / PSA zai ba abokan ciniki kwarin gwiwa da tabbacin ɗaukar matakan tsaro na IoT da keɓaɓɓun na'urori, da kayan masarufi na masana'antu don masana'antu 4.0."

Tsaro yana tallafawa ta hanyar nau'ikan injin din 'Renesas' na Ingantaccen Tsarin Injiniya - tare da (7) ko ba tare da (5) damar asymmetric. Amintaccen Injin Crypto 9 - tare da tsayayya da hare-hare ta kan-gefe, zai isa shekara mai zuwa

Don tsaro na IoT, kamfanin ya hada da nau'ikan ingantaccen aikin injin din Crypto dinsa (duba ginshiƙi) tare da NIST CAVP certifications a saman 'Arm TrustZone for Armv8-M' Virtisation.
