Renesas Electronics Corporation today announced the release of a new RL78/F13 and RL78/F14 16 -bit microcontroller (MCU), these two micro controller can improve vehicle control system development efficiency and reduce system costs, reduce energy consumption and enhancements security features. MCU launched a new product contains a total of 91 models , 60 of which belong to RL78/F13 product group models , 31 models belonging RL78/F14 products group. RL78/F13 MCU for a variety of automotive applications , including power windows and mirrors control, vehicle control systems, and electric water pump and cooling fan and other automotive motor control system . RL78/F14 MCU can support a variety of body control system applications , such as BCM ( Body Control Module ) and HVAC ( heating, ventilation and air conditioning ) control and other memory intensive applications . RL78/F13 and RL78/F14 MCU 's main features : ( A ) a broad product line, can be easily achieved platform standardization , improve development efficiency Because different system specifications vary , to ROM reapplied to other different systems , you need to change the size , in order to meet this demand , the new MCU are integrated with the same CPU core , and has automotive network ( eg CAN ( controller Area Network ) and LIN ( local Interconnect Network ) ) and pin layout and other peripheral functions. For example , RL78/F13 MCU 's internal flash memory size of 16 to 128 kilobytes (KB), packaged as 20-80 pin ; RL78/F14 MCU 's internal flash memory size of 48 to 256 KB, packaged range of 30 to 100-pin , RAM capacity of the largest 20 KB. With such a rich product line , RL78/F13 and RL78/F14 MCU can support a wide range of application requirements. This way , you can reuse the software and through the printed circuit boards and other assets to build a development platform designed to improve the overall efficiency of system development . In addition , RL78/F13 and RL78/F14 MCU also integrates existing Renesas Electronics 78K0R and R8C CPU core , high-performance MCU peripheral functions . So it allows system manufacturers in the effective utilization of existing assets at the same time , thanks to the newly added CPU cores multiply-add instruction and improve system performance. ( 2 ) compact package, supports up to 150 ℃ high temperature operating environment , can reduce the overall cell size To meet the smaller and more compact ECU needs, Renesas Electronics has developed a new QFN ( quad flat no-lead ) package. Phase Renesas Electronics 'existing 32-pin SSOP package ( narrow spacing small outline package ) , the new QFN package mounting area can be reduced by approximately 69% , while Renesas Electronics' existing QFN package compared to the new QFN encapsulated in a side surface of a pin recess , in order to improve welding adhesion during installation , can be achieved without modification factory production line to install the new MCU devices . After the introduction of new QFN package , can reduce the size of the printed circuit board , in order to achieve miniaturization of the whole system ECU . In addition , in order to achieve a higher level of system miniaturization, the market for the MCU mounted on the actuator mechanical and electronic components increasingly strong unified voice , however , such as in pumps and other applications, working conditions, ambient temperature (Ta) will to achieve a relatively high level , so the MCU is difficult to apply the existing condition of the application . And RL78/F13 and RL78/F14 MCU can be up to 150 ℃ ambient temperature to work , so you can directly into the actuator , thus further improving the level of system miniaturization . ( 3 ) 50% reduction in standby power consumption , to achieve low power system design By using lower current consumption in standby mode , RL78/F13 and RL78/F14 MCU standby current phase existing 78K0R/Fx3 MCU Renesas Electronics has declined by 50 per cent, from 1μA ( microamps ) down to 0.5μA ( microamps ) . New MCU also has a case without activating the CPU performs A / D conversion functions , thereby further reducing energy consumption . ( 4 ) abundant hardware features that ensure functional safety For the safety of the structure can improve the electrical or electronic fault detection, thereby protecting the security of the system , and this feature , in the efforts to achieve the ISO 26262 functional safety standard automotive systems extremely helpful , while the market for Join the MCU internal self-diagnostic function increasingly strong demand . RL78/F13 and RL78/F14 MCU contains a wide variety of hardware features to ensure security of the following functions : the reference voltage or supply voltage conversion, and conversion results are compared with the standard value to determine the A / D converter operates normal detection function ; using the interrupt stack overflow detection to prevent runaway software functions ; through the external clock oscillator is compared with the internal oscillator , external clock oscillator is stopped detecting function . Pricing and Availability Renesas Electronics' new RL78/F13 and RL78/F14 MCU will start in October 2013 to provide samples . Based on memory capacity , package type and pin number of different , product pricing will differ. For example, flash memory 128 KB, 48-pin package RL78/F14 MCU is priced at $ 6.0 per piece ( sample ) . Volume production scheduled for September 2014 and is expected in September 2015 reached 2,500,000 pieces per month consolidated production.
