Analog Devices Silent Switcher

Analog Devices has announced the LTM8074, a 1.2A, 40VIN µModule step-down regulator in a 4mm × 4mm × 1.82mm, 0.65mm pitch BGA package. Its total solution size is 60mm2 for 3.2VIN-40VIN, 3.3VOUT requiring only two 0805 capacitors and two 0603 resistors.

The low profile and light-weight (0.08g) package permits the device to be assembled on the backside of PCB where the topside is often very densely populated. Its Silent Switcher architecture minimizes EMI emissions, enabling the LTM8074 to pass CISPR22 class B, and reduce the possibility of EMC susceptibility to other sensitive circuits.

Maxim Cryptographic Engine

Maxim has released its DS28E50 DeepCover secure hash algorithm 3 (SHA3-256) authenticator IC. With SHA3-256, the DS28E50 facilitates challenge-and-response authentication, providing a strong defense against counterfeiting, unauthorized usage and other application problems in a secure IC solution suited for teams with limited or no cryptography expertise.

The DS28E50 also integrates Maxim’s ChipDNA physically unclonable function (PUF) technology to prevent the IC-level attacks that are routinely attempted on security ICs. With ChipDNA technology, which is derived from the naturally occurring random analog characteristics of fundamental MOSFET devices, secret keys that protect all DS28E50 stored data are generated only when needed and are never stored on the chip.

Samsung has launched its Exynos Auto line of image processors. The line is comprised of three sub-categories: Exynos Auto V series for in-vehicle infotainment (IVI) systems; Exynos Auto A series for ADAS; and Exynos Auto T series for telematics devices.

Exynos Auto meets industry requirements for harsher environments, allowing automotive manufacturers to develop modern applications such as infotainment, advanced driving assistance systems (ADAS) and other systems.

Synopsys has unveiled its DesignWare Memory Interface IP family, supporting the next-generation DDR5 and LPDDR5 SDRAMs. The DDR5 and LPDDR5 IP increase memory interface bandwidth compared to DDR4 and LPDDR4 SDRAM interfaces, while reducing area and improving power efficiency.

The DesignWare DDR5 IP, operating at up to 4800 Mbps data rates, can interface with multiple DIMMs per channel up to 80 bits wide, providing a rapid DDR memory interface system for artificial intelligence and data center system-on-chips (SoCs).

Texas Instruments (TI) has introduced a temperature sensor family that offers ±0.1°C accuracy across a large temperature range and helps simplify system design for industrial and medical applications.

The TMP117 single-chip temperature sensor provides similar performance to platinum resistance temperature detectors (RTDs) while reducing design complexity and power consumption, and the TMP117M, a digital temperature sensor for medical applications, supports requirements for medical thermometers. The devices allow engineers to quickly develop accurate, low-power patient monitoring, field transmitter and metering applications.
