renesas公司的78k0/k2l是8位单片mcu,采用78k0兵cpu内核,工作电压1.8v-5.5v,最大频率10mhz,集成了4kb-16kb闪存和384b-768b ram,适用于电池供电系统及节能家电领域，例如测量仪表、感测接口、烟雾传感器、火灾报警器、电动牙刷、剃须刀等。而采用采用78k0/k2l 8位mcu的带蓝牙连接数码相框能很方便地从数码相机,手机和pc中传输照片.本文介绍了8位mcu 78k0/k2l主要特性,方框图, 入门板tk-78k0/kc2l主要特性以及数码相框系统框图和推荐使用的元器件.
digital photo frames display digital photos, and their popularity is evident by the huge variety of such products now on the market. recently, models with network functionality, such as bluetooth or wireless lan connectivity, have appeared. a digital photo frame with bluetooth connectivity makes it easy to transfer photos wirelessly from digital cameras, mobile phones, and pcs, and the extra convenience that these products deliver is driving sales.
to facilitate new designs for digital photo frame applications, renesas electronics offers the 78k0/kx2-l and r8c/3x series of mcus. we also supply peripheral devices such as usb controllers. the cb-40, 55, and 90 series are recommended for the image processing component.
8位mcu 78k0/k2l主要特性:
power supply voltage: vdd = 1.8 to 5.5 v
max. frequency: 10 mhz
rom capacities: 4 kb to 16 kb flash memory
ram capacities: 384 bytes to 768 bytes
20-pin plastic ssop package
78k0 cpu core
low power consumption (vdd = 3.0 v)
- internal high-speed oscillation mode: 260 µa (typ.) (at fcpu = 1 mhz operation)
- stop mode: 0.7 µa (typ.) (at fil = 30 khz operation) clock
- high-speed system clock ... selected from the following three source
- ceramic/crystal oscillator: 1 to 10 mhz
- external clock: 1 to 10 mhz
- internal high-speed oscillator: 4 mhz ± 2 % (-20 to +70℃), or 8 mhz ± 5 %(-40 to +85℃)
- low-speed system oscillator 30 khz ± 10 % ... watchdog timer, timer clock in intermittent operation
- subsystem clock: clock to operate the real-time counter mainly i/o ports:24 (cmos i/o: 21, cmos input: 3) timer
- 16-bit timer/event counter ... timer output, capture input: 1 channel
- 8-bit timer h ... pwm output: 1 channel
- 8-bit timer/event counter 5 ... pwm output, external event counter input: 1 chennel
- watchdog timer ... operable with low-speed internal oscillation clock: 1 chennel serial interface
- uart ... asynchronous 2-wire serial interface: 1 chennel
- iica ... clock synchronous 2-wire serial interface, multimaster supported, standby can be released upon address match in slave mode: 1 channel 10-bit resolution a/d conversion: 6 chennels operational amplifier (products with operational amplifier only): 2 channels power-on-clear (poc) circuit low-voltage detector (lvi) (an interrupt/reset (selectable) is generated when the detection voltage is reached))
- detection voltage: selectable from sixteen levels between 1.91 and 4.22 v single-power-supply flash memory
- flash self programming enabled
- software protection function: protected from outside party copying (no flash reading command) safety function
- watchdog timer operated by clock independent from cpu ... a hang-up can be detected even if the system clock stops
- supply voltage drop detectable by lvi ... appropriate processing can be executed before the supply voltage drops below the operation voltage
- equipped with option byte function ... important system operation settings set in hardware on-chip debug function ... available to control for the target device, and to reference memory operating ambient temperature: ta = -40 to +85℃
