1.0 General Description
MG87FE/L52
MG87FE/L52 is a single-chip 8 bits microcontroller with the instruction sets fully compatible
with industrial-standard 80C51 series microcontroller. 8K bytes flash memory and 256 bytes
RAM has been embedded to provide wide field application. In-System-Programming and
In-Application-Programming allow the users to download new code or data while the
microcontroller sits in the application. This device executes one machine cycle in 6 clock or 12
clock cycles. MG87FE/L52 has four 8-bit I/O ports, one 4-bit I/O ports, three 16-bit
timer/counters, an eight-source, four-priority-level interrupt structure, an enhanced UART,
on-chip crystal oscillator.
Excellent flash-endurance, flash-retention, and code-protecting security make MG87FE/L52 as
an excellent micro-controller.
2.0 Features
80C51 Central Processing Unit
8KB On-Chip program memory for program ROM, ISP ROM & IAP zone.
ISP capability; optional 0.5K/1KB/1.5K~3.5KB ISP memory shared with 8KB flash memory.
IAP capability; program controlled IAP memory size shared with 8KB flash memory.
On-Chip 256 bytes scratch-pad RAM. Also, the MCU can address up to 64K bytes external
memory.
MOVC-disabling, encrypting, and locking flash memory realize security mechanism.
Three 16-bits timer/counter, Timer2 is an up/down counter with programmable clock output
on P1.0
Eight sources, four-level-priority interrupt capability
Enhanced UART, provides frame-error detection and hardware address-recognition
Dual DPTR for fast-accessing of data memory
15 bits Watch-Dog-Timer with 8-bits pre-scaler, one-time enabled
Low EMI: inhibits ALE emission
Power control: Idle mode and Power-Down mode; Power-Down can be woken-up by
P3.2/P3.3/P4.2/P4.3, Idle mode could be woken up by all interrupt sources.
I/O port: 32+4 I/O ports :
-
PDIP-40 (MG87FE/L52AE or MG87FE/L52GE) has 32 I/O ports;
