UPD78P058GC-8BT

The UPD78P058GC-8BT is a kind of 8-bit single-chip microcontroller. The on-chip mask ROM of the UPD78P058GC-8BT is replaced with one-time PROM or EPROM. Because it can be programmed by users, it is ideally suited for applications involving the evaluation of systems in development stages, small-scale production of many different products, and rapid development and time-to-market of a new product. Besides, it is available in 80-pin plastic QFP package.
 
There are some features of UPD78P058GC-8BT. (1) pin compatible with mask ROM versions (except the VPP pin); (2)  internal high-capacity PROM and RAM: 64 Kbytes PROM, 1024 bytes high-speed RAM, 32 bytes buffer RAM and 1024 bytes expansion RAM; (3) operable in the same supply voltage as mask ROM versions (VDD=2.0 to 6.0 V); (4) corresponding to QTOPTM microcontrollers.

What comes next is about the absolute maximum ratings of UPD78P058GC-8BT. (1): VDD (supply voltage) is from -0.3 to +7.0 V; (2): VPP (supply voltage) is from -0.3 to +13.5 V; (3): AVDD (supply voltage) is from -0.3 to VDD+0.3 V; (4): AVREF0 (supply voltage) is from -0.3 to VDD+0.3 V; (5): AVREF1 (supply voltage) is from -0.3 to VDD+0.3 V; (6): AVSS (supply voltage) is from -0.3 to +0.3 V; (7): VO (output voltage) is from -0.3 to VDD+0.3 V; (8): VAN (analog input voltage) is from AVSS-0.3 to VREF0+0.3 V for P10 to P17 (analog input pins); (9): TA (operating ambient temperature) is from -40 to +85; (10): Tstg (storage temperature) is from -65 to +150.
