80C51 Central Processing Unit
MG87FE(L)04 with 4KB flash ROM (Built-in Megawin standard ISP & UART COMBO ISP code with auto switching)
Operating voltage: E type: 4.5V~5.5V and L type: 2.4V~3.6V
Operating frequency:
- Internal RC-oscillator (default 22.118Mhz@12T)
- +/- 1% frequency drift @ 25℃
- +/- 2% frequency drift @ -20 ~ 50℃
- +/- 4% frequency drift @ -40 ~ 85℃
IAP capability; 2KB IAP memory size
On-chip 256 bytes data RAM
Code protection for flash memory access
Two 16-bit timer/counter
PWM-Timer for PWM generator or normal 8-bit timer, selectable interrupt source
Enhanced UART, provides frame-error detection and hardware address-recognition
15 bits Watch-Dog-Timer with 8-bit pre-scalar, one-time enabled by CPU or power-on
Power control: idle mode and power-down mode, Power-down can be woken-up by INT0(P3.2), INT2(P4.3), and other I/O.
I/O port list, P1.5 (P3.5/T1), P1.3 (P4.3/INT2), P1 [1:0] and P3 [2:0].
Built-in analog comparator with selectable interrupt on INT2. AIN0(V+) on P1.0 and AIN1(V-) on P1.1, output on P3.6(internal port)
