When the future meets the past
This month, Microchip revives an ARM classic in a hot-rod skin: 600MHz of adrenaline packed with a 24b LCD controller, camera interface and a class-D amplifier. At the same time, NXP beefs up its LPC55xx family and prefers to stick to the more recent (2016) and secure Cortex-M33. The future meets the past this month.
Microchip added 36 variant of existing parts. The ATTiny 102/104 got a F extension for a fast startup time option, while the PIC16LF, PIC18LF and DSPIC33EP512 got their share of variants too.
But the most interesting change was the launch of the SAM9X60. The SAM9X60 sports a (wow) 600 MHz ARM926EJ-S with support for 16-bit LPDDR/DDR2, 32-bit LPSDR/SDRAM, NAND flash, Quad SPI and eMMC Flash. There is also a Secure Boot capability with on-chip secure key storage (OTP), high-performance crypto accelerators (SHA, AES and TDES) as well as tamper pins. For the younger folks, the ARM9 was created in 1998, so the appetite for Microchip to continue the classic ARM9 maybe a very low royalty rate. Additional features include:
- 32/32 kB Data/Inst Cache
- 64 kB internal SRAM
- 24-bit LCD Controller with overlays up to 1024×768 resolution
- 2D Graphics Engine, Camera Interface
- Built-in Class D Amplifier
- Dual 10/100 Ethernet, Dual CAN, Dual SD Card/eMMC
- Two High-speed USB Host + One High-speed Host or Device
- Thirteen FLEXCOMs (USART, SPI and I²C)
- TFBGA228, 11×11, 0.65 mm pitch
Prices start at $4.67/10k.
M032LE3AE and M032SE3AE had their parametrics removed this month. Some challenges on this product line?
NXP has beefed up its LPC5500 series portfolio with another 16 parts. It is marked as in production but the site also mentions that “The remaining LPC5500 MCU series will be sampling throughout 2019-2020”. The series uses a 40nm process, and is based on the Cortex-M33 using the latest security features such as SRAM PUF-based root of trust and provisioning, real-time execution from encrypted images (internal flash), and asset protection with Arm TrustZone-M. Interestingly, it integrates a power management IC (DC-DC) and dedicated co-processors for signal processing and cryptographic acceleration.
Here is an overview of the ‘available’ series.
- LPC55(S)6X: 100 or 150MHz, 320 or 640 KB of Flash and 2 USB controllers at -40-105C, S version embeds all the security functions
- LPC55(S)2X: 100 or 150MHz, 256 or 512 KB of Flash and 2 USB controllers at -40-105C, S version embeds all the security functions
- LPC55(S)1X: In preproduction, lower cost version with up to 256 kB of Flash, one or 2 USB controllers, little information available
NXP also added the LPC804UK, the bigger brother of the existing LPC802UK. Their distinctive feature is a WLCSP package.
In the RL78 family, the F14 added 31 additional parts. These are available in a 30 to 100-pin, 48 to 256 KB flash memory lineup, have a built-in CAN module and LIN module for automotive interfaces, and also support BLDC motor control using the RL78/F13’s functional safety features, timer RD, comparator, and D/A converter. Same treatment for the F13 with 60 additional parts. Both are derived from automotive grade parts and have extended temperature range available (-40 to 105/125 and 150C).
On the RX side, the RX23E-A came out with 8 parts, equipped with a RXv2 core and an analog front end that can measure temperature, pressure, flow, and weight with less than 0.1% precision without calibration, making it ideal for high-precision sensing, test and measurement equipment. Other variants were added to the RX24T, RX24U, RX62T, RX651 and RX566T.
Renesas re-added the S5D3 group (120 MHz, 520kB Flash) from the portfolio. It was likely a glitch on the website.
No change this month.
Nothing significant this month.
ST disclosed a few variants of existing parts, nothing earth shaking.
