The MCU can be connected to an SLC NAND Flash memory with capacity ranging from 4Gb to 1Gb, and it includes 4- and 8-bit error correction circuits to detect and correct hardware errors. The IC also has a watchdog timer that operates along with a built-in clock separate from the system clock. This enables the watchdog timer to detect an error even if the system clock malfunctions.<\/p>\n<p>The TMPM46BF10FB is housed in a LQFP100 package (14mm x 14mm x 0.5 mm pitch). Operating voltage ranges from 2.7V to 3.6V, with maximum operating frequency of 120MHz.<\/p>\n<p>Other features of the new MCU include an encryption\/decryption circuit (AES:FIPS197 standard), Hash function generation circuit (SHA: FIPS180-4 standard), and random seed generation circuit (ESG). Encryption\/decryption is mainly processed by hardware, reducing the load on the CPU. The IC also implements a true random number generator (TRNG: SP800-90C standard) through the combination of the random seed generation circuit and Hash-DRGB created by the hash function generation circuit and the software program. This achieves the robust security function that is required in network communications.<\/p>\n<p>Samples of the TMPM46BF10FG microcontroller have begun shipping. Mass production is slated to start in October 2015.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Designed for secure communications control, the TMPM46BF10FG incorporates 514-Kbyte SRAM, four security circuits for network communications, and a single-level cell (SLC) NAND Flash memory controller for memory expansion.<\/p>\n","protected":false},"author":6,"featured_media":8449,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[19,1779],"tags":[2804,2806,2805,191,2803],"class_list":["post-8448","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-headlines","category-headlines-2","tag-arm-cortex","tag-mcu","tag-tmpm46bf10fg","tag-toshiba","tag-toshiba-america-electronic-components-inc"],"_links":{"self":[{"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/posts\/8448","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/comments?post=8448"}],"version-history":[{"count":0,"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/posts\/8448\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/media\/8449"}],"wp:attachment":[{"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/media?parent=8448"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/categories?post=8448"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.upgrademag.com\/web\/wp-json\/wp\/v2\/tags?post=8448"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
