Lelapa la Renesas Cortex-M MCU le eketsa ts'ireletso bakeng la IoT le ts'ehetso ea tikoloho
Ba bitsoa ba lelapa la RA, ke ba PSA Certified Level 1 mme ba tla ka mekhahlelo e mene:
- RA2 Series - Cortex-M23 ho fihlela ho 60 MHz
- RA4 Series - Cortex-M4 ho fihlela 48MHz (kapa 100MHz, feme e buile ka bobeli)
- RA6 Series - Cortex-M4 ho fihlela ho 120MHz (ho fihlela ho 200 MHz)
- RA8 Series - e tla lokolloa hamorao - Dual 200MHz cores
Hona ho batla ho tšoana le lelapa la Renesas 'le leng teng la RS' Synergy '?
Ho joalo, ho lumellana le motsamaisi oa thekiso ea Renesas Tim Burgess, empa li-Synergy MCU li tšoaneleha ho sebelisoa le lelapa le koaletsoeng la lisebelisoa le lisebelisoa - hammoho ba theha 'Synergy Platform' - ha lisebelisoa tsa mokha oa 3 li ka sebelisoa le lisebelisoa tsa RA.
Empa na ke silicon e tšoanang?
"Ha re batle ho senola seo," Burgess o bolelletse Electronics Weekly, mme a eketsa: "Ho na le lisebelisoa tse ngata tsa RA tse ncha tseo u sa li fumaneng tse tšoanang le lisebelisoa tsa Synergy."
Bakeng sa RA MCUs, Renesas e se e bokellelitse mohokahanyi oa tikoloho ho tlisa software le lisebelisoa ho li tšehetsa.
"RA Family 'software e bonolo ea" software "[FSP] e fana ka moralo o bulehileng o lumellang bareki ho sebelisa mokhoa oa bona oa lefa le ho o kopanya le mehlala ea software e tsoang ho Renesas le balekane ba tikoloho ho potlakisa ts'ebetso ea mesebetsi e rarahaneng joaloka khokahano le polokeho," ho latela ho Renesas. "FSP e na le FreeRTOS ea Amazon mme e tla eketsa tšehetso ea ThreadX RTOS le middleware ho Cortex-M23 le Cortex-M33 MCUs qalong ea 2020, e fana ka sesebelisoa sa marang-rang bakeng sa bahlahisi. Likhetho tsena tse tsoang ka lebokoseng li ka fetoloa habonolo 'me tsa eketsoa ka RTOS kapa li-middleware tse ling. ”
Pele-up - Lisebelisoa tsa RA8 le Cortex-M33 li tla hamorao
32 RA MCUs li lokollotsoe kajeno, ka lihlopha tse hlano, li arotsoe har'a lihlooho tse tharo - ka puo ea Renesas.
Ba fana ka khetho ea Cortex-M4 kapa Cortex-M23, lipinara tsa lipakete ho tloha 32 ho isa ho 176, lipakeng tsa 256kbyte le 2Mbyte ea Flash, le 32 ho isa ho 640kbyte ea RAM.
Likhetho tsa khokahano li kenyelletsa USB, CAN, Ethernet le capacitive touch sensing.
Ka 2020, 'mapa oa tsela o bolela esale pele lisebelisoa tse tsoetseng pele haholo ho kenyeletsa likarolo tsa mantlha tsa RA8 le likhetho tsa Cortex-M33.
"Roadmap e fana ka lisebelisoa tse lumellanang tsa PSA Certified-Trust & Firmware-M [TF-M], ho kenyelletsa li-Cortex-M33 MCUs, li-Cortex-M23 MCUs tse se nang motlakase, le lihlahisoa tse se nang mohala tsa Bluetooth IEE 802.15.4," ho latela Renesas. "Li-MCU tse nang le tumello ea TF-M / PSA li tla fa bareki kholiseho le tiiso ea ho tsamaisa lisebelisoa tsa IoT tse bolokehileng le lisebelisoa tse haufi, le lisebelisoa tsa fektheri tse bohlale tsa indasteri ea 4.0."
Ts'ireletso e tšehelitsoe ke mefuta ea Renesas 'Sephiri sa Ts'ireletso sa Renesas - le (7) kapa ntle le (5) bokhoni ba asymmetric. Ts'ireletso ea Crystal e bolokehileng ea 9 - e hanyetsang litlhaselo tsa litla-morao, e tla fihla selemong se tlang
Bakeng sa ts'ireletso ea IoT, feme e kenyelelitse mefuta ea Enjini ea eona e Sireletsehileng ea Crystal (bona chate) e nang le li-certification tsa NIST CAVP ka holimo ho 'Arm TrustZone bakeng sa Armv8-M'.
Thibelo ena ea polokeho (ho latela mofuta oa phetolelo) e fana ka melaetsa e meng le e meng ka mokhoa oa eona oa ho ngola le ho ngola lintho ka mokhoa o hlakileng, mesebetsi ea hash, tlhaiso ea linomoro tsa 'nete (TRNG), le ho sebetsana le senotlolo - ho kenyeletsoa mokhoako oa mantlha oa bohlophisi ba MCU.
"Tsamaiso ea taolo ea phihlello e koala enjene ea chelete haeba protocol e nepahetseng ea phihlello e sa lateloe, 'me RAM e ikemiselitseng e tiisa hore linotlolo tsa mongolo o hlakileng ha ho mohla li pepesetsoang CPU kapa bese e parolang."
Ho nolofalletsa nts'etsopele, o thusa tikoloho ea nts'etsopele ea lelapa RA ho fana ka debug de-chip, li-IDE, moqapi, lisebelisoa tsa tšehetso, lisebelisoa tsa tlhahlobo ea boto, lifaele tsa moralo, schematics, marang-rang a PCB le BOM.
